+   * @ingroup functors
+   *
+   *  Binders turn functions/functors with two arguments into functors
+   *  with a single argument, storing an argument to be applied later.
+   *  For example, a variable @c B of type @c binder1st is constructed
+   *  from a functor @c f and an argument @c x. Later, B's @c
+   *  operator() is called with a single argument @c y. The return
+   *  value is the value of @c f(x,y). @c B can be @a called with
+   *  various arguments (y1, y2, ...) and will in turn call @c
+   *  f(x,y1), @c f(x,y2), ...
+   *
+   *  The function @c bind1st is provided to save some typing. It takes the
+   *  function and an argument as parameters, and returns an instance of
+   *  @c binder1st.
+   *
+   *  The type @c binder2nd and its creator function @c bind2nd do the same
+   *  thing, but the stored argument is passed as the second parameter instead
+   *  of the first, e.g., @c bind2nd(std::minus<float>,1.3) will create a
+   *  functor whose @c operator() accepts a floating-point number, subtracts
+   *  1.3 from it, and returns the result. (If @c bind1st had been used,
+   *  the functor would perform <em>1.3 - x</em> instead.
+   *
+   *  Creator-wrapper functions like @c bind1st are intended to be used in
+   *  calling algorithms. Their return values will be temporary objects.
+   *  (The goal is to not require you to type names like
+   *  @c std::binder1st<std::plus<int>> for declaring a variable to hold the
+   *  return value from @c bind1st(std::plus<int>,5).
+   *
+   *  These become more useful when combined with the composition functions.

+   * These algorithms are variations of a classic binary search, and

+   * 
+   * The number of comparisons will be logarithmic (and as few as
+   * possible).  The number of steps through the sequence will be
+   * logarithmic for random-access iterators (e.g., pointers), and
+   * linear otherwise.
+   * 
+   * The LWG has passed Defect Report 270, which notes: <em>The
+   * proposed resolution reinterprets binary search. Instead of
+   * thinking about searching for a value in a sorted range, we view
+   * that as an important special case of a more general algorithm:
+   * searching for the partition point in a partitioned range.  We
+   * also add a guarantee that the old wording did not: we ensure that
+   * the upper bound is no earlier than the lower bound, that the pair
+   * returned by equal_range is a valid range, and that the first part
+   * of that pair is the lower bound.</em>
+   *
+   * The actual effect of the first sentence is that a comparison
+   * functor passed by the user doesn't necessarily need to induce a
+   * strict weak ordering relation.  Rather, it partitions the range.

+   *
+   *  A string looks like this:
+   *
+   *  @code
+   *                                        [_Rep]
+   *                                        _M_length
+   *   [basic_string<char_type>]            _M_capacity
+   *   _M_dataplus                          _M_refcount
+   *   _M_p ---------------->               unnamed array of char_type
+   *  @endcode
+   *
+   *  Where the _M_p points to the first character in the string, and
+   *  you cast it to a pointer-to-_Rep and subtract 1 to get a
+   *  pointer to the header.
+   *
+   *  This approach has the enormous advantage that a string object
+   *  requires only one allocation.  All the ugliness is confined
+   *  within a single %pair of inline functions, which each compile to
+   *  a single @a add instruction: _Rep::_M_data(), and
+   *  string::_M_rep(); and the allocation function which gets a
+   *  block of raw bytes and with room enough and constructs a _Rep
+   *  object at the front.
+   *
+   *  The reason you want _M_data pointing to the character %array and
+   *  not the _Rep is so that the debugger can see the string
+   *  contents. (Probably we should add a non-inline member to get
+   *  the _Rep for the debugger to use, so users can check the actual
+   *  string length.)
+   *
+   *  Note that the _Rep object is a POD so that you can have a
+   *  static <em>empty string</em> _Rep object already @a constructed before
+   *  static constructors have run.  The reference-count encoding is
+   *  chosen so that a 0 indicates one reference, so you never try to
+   *  destroy the empty-string _Rep object.
+   *
+   *  All but the last paragraph is considered pretty conventional
+   *  for a C++ string implementation.

+       *  set the state to initialized conditions.

+   *  @brief  Class defining multi-dimensional subset of an array.
+   *
+   *  The slice class represents a multi-dimensional subset of an array,
+   *  specified by three parameter sets: start offset, size array, and stride
+   *  array.  The start offset is the index of the first element of the array
+   *  that is part of the subset.  The size and stride array describe each
+   *  dimension of the slice.  Size is the number of elements in that
+   *  dimension, and stride is the distance in the array between successive
+   *  elements in that dimension.  Each dimension's size and stride is taken
+   *  to begin at an array element described by the previous dimension.  The
+   *  size array and stride array must be the same size.
+   *

+   *
+   *  An indirect_array is a reference to the actual elements of an array
+   *  specified by an ordered array of indices.  The way to get an
+   *  indirect_array is to call operator[](valarray<size_t>) on a valarray.
+   *  The returned indirect_array then permits carrying operations out on the
+   *  referenced subset of elements in the original valarray.
+   *
+   *  For example, if an indirect_array is obtained using the array (4,2,0) as
+   *  an argument, and then assigned to an array containing (1,2,3), then the
+   *  underlying array will have array[0]==3, array[2]==2, and array[4]==1.
+   *
+   *  @param  Tp  Element type.

+   *  to as @a node in this file.  It is a simple array-of-Tp.  If Tp
+   *  is very large, there will be one Tp element per node (i.e., an
+   *  @a array of one).  For non-huge Tp's, node size is inversely
+   *  related to Tp size: the larger the Tp, the fewer Tp's will fit
+   *  in a node.  The goal here is to keep the total size of a node
+   *  relatively small and constant over different Tp's, to improve
+   *  allocator efficiency.
+   *
+   *  Not every pointer in the %map array will point to a node.  If
+   *  the initial number of elements in the deque is small, the
+   *  /middle/ %map pointers will be valid, and the ones at the edges
+   *  will be unused.  This same situation will arise as the %map
+   *  grows: available %map pointers, if any, will be on the ends.  As
+   *  new nodes are created, only a subset of the %map's pointers need
+   *  to be copied @a outward.
+   *
+   *  Class invariants:
+   * - For any nonsingular iterator i:
+   *    - i.node points to a member of the %map array.  (Yes, you read that
+   *      correctly:  i.node does not actually point to a node.)  The member of
+   *      the %map array is what actually points to the node.
+   *    - i.first == *(i.node)    (This points to the node (first Tp element).)
+   *    - i.last  == i.first + node_size
+   *    - i.cur is a pointer in the range [i.first, i.last).  NOTE:
+   *      the implication of this is that i.cur is always a dereferenceable
+   *      pointer, even if i is a past-the-end iterator.
+   * - Start and Finish are always nonsingular iterators.  NOTE: this
+   * means that an empty deque must have one node, a deque with <N
+   * elements (where N is the node buffer size) must have one node, a
+   * deque with N through (2N-1) elements must have two nodes, etc.
+   * - For every node other than start.node and finish.node, every
+   * element in the node is an initialized object.  If start.node ==
+   * finish.node, then [start.cur, finish.cur) are initialized
+   * objects, and the elements outside that range are uninitialized
+   * storage.  Otherwise, [start.cur, start.last) and [finish.first,
+   * finish.cur) are initialized objects, and [start.first, start.cur)
+   * and [finish.cur, finish.last) are uninitialized storage.
+   * - [%map, %map + map_size) is a valid, non-empty range.
+   * - [start.node, finish.node] is a valid range contained within
+   *   [%map, %map + map_size).
+   * - A pointer in the range [%map, %map + map_size) points to an allocated
+   *   node if and only if the pointer is in the range
+   *   [start.node, finish.node].
+   *
+   *  Here's the magic:  nothing in deque is @b aware of the discontiguous
+   *  storage!
+   *
+   *  The memory setup and layout occurs in the parent, _Base, and the iterator
+   *  class is entirely responsible for @a leaping from one node to the next.
+   *  All the implementation routines for deque itself work only through the
+   *  start and finish iterators.  This keeps the routines simple and sane,
+   *  and we can use other standard algorithms as well.

+   * @ingroup utilities
+   *
+   *  Function objects, or @e functors, are objects with an @c operator()
+   *  defined and accessible.  They can be passed as arguments to algorithm
+   *  templates and used in place of a function pointer.  Not only is the
+   *  resulting expressiveness of the library increased, but the generated
+   *  code can be more efficient than what you might write by hand.  When we
+   *  refer to @a functors, then, generally we include function pointers in
+   *  the description as well.
+   *
+   *  Often, functors are only created as temporaries passed to algorithm
+   *  calls, rather than being created as named variables.
+   *
+   *  Two examples taken from the standard itself follow.  To perform a
+   *  by-element addition of two vectors @c a and @c b containing @c double,
+   *  and put the result in @c a, use
+   *  \code
+   *  transform (a.begin(), a.end(), b.begin(), a.begin(), plus<double>());
+   *  \endcode
+   *  To negate every element in @c a, use
+   *  \code
+   *  transform(a.begin(), a.end(), a.begin(), negate<double>());
+   *  \endcode
+   *  The addition and negation functions will be inlined directly.
+   *
+   *  The standard functors are derived from structs named @c unary_function
+   *  and @c binary_function.  These two classes contain nothing but typedefs,
+   *  to aid in generic (template) programming.  If you write your own
+   *  functors, you might consider doing the same.

+   *  and return an instance of @c unary_negate or

+   *
+   *  std::find_if (v.begin(), v.end(), not1(IntGreaterThanThree()));
+   *  \endcode
+   *  The call to @c find_if will locate the first index (i) of @c v for which
+   *  <code>!(v[i] > 3)</code> is true.
+   *
+   *  The not1/unary_negate combination works on predicates taking a single

+   *  Meets the requirements of a <a href="tables.html#65">container</a>, a
+   *  <a href="tables.html#66">reversible container</a>, and a
+   *  <a href="tables.html#67">sequence</a>, including the

+   *  %exception of @c at and @c operator[].
+   *
+   *  This is a @e doubly @e linked %list.  Traversal up and down the
+   *  %list requires linear time, but adding and removing elements (or
+   *  @e nodes) is done in constant time, regardless of where the
+   *  change takes place.  Unlike std::vector and std::deque,
+   *  random-access iterators are not provided, so subscripting ( @c
+   *  [] ) access is not allowed.  For algorithms which only need
+   *  sequential access, this lack makes no difference.
+   *
+   *  Also unlike the other standard containers, std::list provides
+   *  specialized algorithms %unique to linked lists, such as
+   *  splicing, sorting, and in-place reversal.
+   *
+   *  A couple points on memory allocation for list<Tp>:
+   *
+   *  First, we never actually allocate a Tp, we allocate
+   *  List_node<Tp>'s and trust [20.1.5]/4 to DTRT.  This is to ensure
+   *  that after elements from %list<X,Alloc1> are spliced into
+   *  %list<X,Alloc2>, destroying the memory of the second %list is a
+   *  valid operation, i.e., Alloc1 giveth and Alloc2 taketh away.
+   *
+   *  Second, a %list conceptually represented as
+   *  @code
+   *    A <---> B <---> C <---> D
+   *  @endcode
+   *  is actually circular; a link exists between A and D.  The %list
+   *  class holds (as its only data member) a private list::iterator
+   *  pointing to @e D, not to @e A!  To get to the head of the %list,
+   *  we start at the tail and move forward by one.  When this member
+   *  iterator's next/previous pointers refer to itself, the %list is
+   *  %empty.

+   *  @brief  The %bitset class represents a @e fixed-size sequence of bits.
+   *
+   *  @ingroup containers
+   *
+   *  (Note that %bitset does @e not meet the formal requirements of a
+   *  <a href="tables.html#65">container</a>.  Mainly, it lacks iterators.)
+   *
+   *  The template argument, @a Nb, may be any non-negative number,
+   *  specifying the number of bits (e.g., "0", "12", "1024*1024").
+   *
+   *  In the general unoptimized case, storage is allocated in word-sized
+   *  blocks.  Let B be the number of bits in a word, then (Nb+(B-1))/B
+   *  words will be used for storage.  B - Nb%B bits are unused.  (They are
+   *  the high-order bits in the highest word.)  It is a class invariant
+   *  that those unused bits are always zero.
+   *
+   *  If you think of %bitset as <em>a simple array of bits</em>, be
+   *  aware that your mental picture is reversed: a %bitset behaves
+   *  the same way as bits in integers do, with the bit at index 0 in
+   *  the <em>least significant / right-hand</em> position, and the bit at
+   *  index Nb-1 in the <em>most significant / left-hand</em> position.
+   *  Thus, unlike other containers, a %bitset's index <em>counts from
+   *  right to left</em>, to put it very loosely.
+   *
+   *  This behavior is preserved when translating to and from strings.  For
+   *  example, the first line of the following program probably prints
+   *  <em>b(&apos;a&apos;) is 0001100001</em> on a modern ASCII system.
+   *
+   *  @code
+   *     #include <bitset>
+   *     #include <iostream>
+   *     #include <sstream>
+   *
+   *     using namespace std;
+   *
+   *     int main()
+   *     {
+   *         long         a = 'a';
+   *         bitset<10>   b(a);
+   *
+   *         cout << "b('a') is " << b << endl;
+   *
+   *         ostringstream s;
+   *         s << b;
+   *         string  str = s.str();
+   *         cout << "index 3 in the string is " << str[3] << " but\n"
+   *              << "index 3 in the bitset is " << b[3] << endl;
+   *     }

+   *  Also see:
+   *  http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt12ch33s02.html
+   *  for a description of extensions.
+   *
+   *  Most of the actual code isn't contained in %bitset<> itself, but in the
+   *  base class _Base_bitset.  The base class works with whole words, not with
+   *  individual bits.  This allows us to specialize _Base_bitset for the
+   *  important special case where the %bitset is only a single word.
+   *
+   *  Extra confusion can result due to the fact that the storage for
+   *  _Base_bitset @e is a regular array, and is indexed as such.  This is
+   *  carefully encapsulated.

+   *
+   *  @param __mangled_name A NUL-terminated character string
+   *  containing the name to be demangled.
+   *
+   *  @param __output_buffer A region of memory, allocated with
+   *  malloc, of @a *__length bytes, into which the demangled name is
+   *  stored.  If @a __output_buffer is not long enough, it is
+   *  expanded using realloc.  @a __output_buffer may instead be NULL;
+   *  in that case, the demangled name is placed in a region of memory
+   *  allocated with malloc.
+   *
+   *  @param __length If @a __length is non-NULL, the length of the
+   *  buffer containing the demangled name is placed in @a *__length.
+   *
+   *  @param __status @a *__status is set to one of the following values:
+   *   0: The demangling operation succeeded.
+   *  -1: A memory allocation failure occurred.
+   *  -2: @a mangled_name is not a valid name under the C++ ABI mangling rules.
+   *  -3: One of the arguments is invalid.
+   *
+   *  @return A pointer to the start of the NUL-terminated demangled
+   *  name, or NULL if the demangling fails.  The caller is
+   *  responsible for deallocating this memory using @c free.
+   *
+   *  The demangling is performed using the C++ ABI mangling rules,
+   *  with GNU extensions. For example, this function is used in
+   *  __gnu_cxx::__verbose_terminate_handler.
+   *
+   *  See http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt12ch39.html
+   *  for other examples of use.
+   *
+   *  @note The same demangling functionality is available via
+   *  libiberty (@c <libiberty/demangle.h> and @c libiberty.a) in GCC
+   *  3.1 and later, but that requires explicit installation (@c
+   *  --enable-install-libiberty) and uses a different API, although
+   *  the ABI is unchanged.

+   * class, and avoid raising compile-time ambiguities.  Because

+   * so that it becomes reusable for creating other pointer types.
+   *
+   * A key point of this class is also that it allows container
+   * writers to 'assume' Alocator::pointer is a typedef for a normal
+   * pointer.  This class supports most of the conventions of a true
+   * pointer, and can, for instance handle implicit conversion to
+   * const and base class pointer types.  The only impositions on
+   * container writers to support extended pointers are: 1) use the
+   * Allocator::pointer typedef appropriately for pointer types.  2)
+   * if you need pointer casting, use the __pointer_cast<> functions
+   * from ext/cast.h.  This allows pointer cast operations to be
+   * overloaded is necessary by custom pointers.
+   *
+   * Note: The const qualifier works with this pointer adapter as
+   * follows:

+   *
+   *  @code
+   *                                        [_Rep]
+   *                                        _M_length
+   *   [__rc_string_base<char_type>]        _M_capacity
+   *   _M_dataplus                          _M_refcount
+   *   _M_p ---------------->               unnamed array of char_type
+   *  @endcode
+   *
+   *  Where the _M_p points to the first character in the string, and
+   *  you cast it to a pointer-to-_Rep and subtract 1 to get a
+   *  pointer to the header.
+   *
+   *  This approach has the enormous advantage that a string object
+   *  requires only one allocation.  All the ugliness is confined
+   *  within a single pair of inline functions, which each compile to
+   *  a single @a add instruction: _Rep::_M_refdata(), and
+   *  __rc_string_base::_M_rep(); and the allocation function which gets a
+   *  block of raw bytes and with room enough and constructs a _Rep
+   *  object at the front.
+   *
+   *  The reason you want _M_data pointing to the character array and
+   *  not the _Rep is so that the debugger can see the string
+   *  contents. (Probably we should add a non-inline member to get
+   *  the _Rep for the debugger to use, so users can check the actual
+   *  string length.)
+   *
+   *  Note that the _Rep object is a POD so that you can have a
+   *  static <em>empty string</em> _Rep object already @a constructed before
+   *  static constructors have run.  The reference-count encoding is
+   *  chosen so that a 0 indicates one reference, so you never try to
+   *  destroy the empty-string _Rep object.
+   *
+   *  All but the last paragraph is considered pretty conventional
+   *  for a C++ string implementation.

+   *  Because properly forward-declaring these classes can be difficult, you

+   *  well as the typedefs.  Trying to forward-declare the typedefs
+   *  themselves (e.g., <code>class ostream;</code>) is not valid ISO C++.

+   *  @brief  The actual work of input and output (interface).
+   *  @ingroup io
+   *
+   *  This is a base class.  Derived stream buffers each control a
+   *  pair of character sequences:  one for input, and one for output.
+   *
+   *  Section [27.5.1] of the standard describes the requirements and
+   *  behavior of stream buffer classes.  That section (three paragraphs)
+   *  is reproduced here, for simplicity and accuracy.
+   *
+   *  -# Stream buffers can impose various constraints on the sequences
+   *     they control.  Some constraints are:
+   *     - The controlled input sequence can be not readable.
+   *     - The controlled output sequence can be not writable.
+   *     - The controlled sequences can be associated with the contents of
+   *       other representations for character sequences, such as external
+   *       files.
+   *     - The controlled sequences can support operations @e directly to or
+   *       from associated sequences.
+   *     - The controlled sequences can impose limitations on how the
+   *       program can read characters from a sequence, write characters to
+   *       a sequence, put characters back into an input sequence, or alter
+   *       the stream position.
+   *     .
+   *  -# Each sequence is characterized by three pointers which, if non-null,
+   *     all point into the same @c charT array object.  The array object
+   *     represents, at any moment, a (sub)sequence of characters from the
+   *     sequence.  Operations performed on a sequence alter the values
+   *     stored in these pointers, perform reads and writes directly to or
+   *     from associated sequences, and alter <em>the stream position</em> and
+   *     conversion state as needed to maintain this subsequence relationship.
+   *     The three pointers are:
+   *     - the <em>beginning pointer</em>, or lowest element address in the
+   *       array (called @e xbeg here);
+   *     - the <em>next pointer</em>, or next element address that is a
+   *       current candidate for reading or writing (called @e xnext here);
+   *     - the <em>end pointer</em>, or first element address beyond the
+   *       end of the array (called @e xend here).
+   *     .
+   *  -# The following semantic constraints shall always apply for any set
+   *     of three pointers for a sequence, using the pointer names given
+   *     immediately above:
+   *     - If @e xnext is not a null pointer, then @e xbeg and @e xend shall
+   *       also be non-null pointers into the same @c charT array, as
+   *       described above; otherwise, @e xbeg and @e xend shall also be null.
+   *     - If @e xnext is not a null pointer and @e xnext < @e xend for an
+   *       output sequence, then a <em>write position</em> is available.
+   *       In this case, @e *xnext shall be assignable as the next element
+   *       to write (to put, or to store a character value, into the sequence).
+   *     - If @e xnext is not a null pointer and @e xbeg < @e xnext for an
+   *       input sequence, then a <em>putback position</em> is available.
+   *       In this case, @e xnext[-1] shall have a defined value and is the
+   *       next (preceding) element to store a character that is put back
+   *       into the input sequence.
+   *     - If @e xnext is not a null pointer and @e xnext< @e xend for an
+   *       input sequence, then a <em>read position</em> is available.
+   *       In this case, @e *xnext shall have a defined value and is the
+   *       next element to read (to get, or to obtain a character value,

+  // Class template _Hashtable, class definition.
+
+  // Meaning of class template _Hashtable's template parameters
+
+  // _Key and _Value: arbitrary CopyConstructible types.
+
+  // _Allocator: an allocator type ([lib.allocator.requirements]) whose
+  // value type is Value.  As a conforming extension, we allow for
+  // value type != Value.
+
+  // _ExtractKey: function object that takes a object of type Value
+  // and returns a value of type _Key.
+
+  // _Equal: function object that takes two objects of type k and returns
+  // a bool-like value that is true if the two objects are considered equal.
+
+  // _H1: the hash function.  A unary function object with argument type
+  // Key and result type size_t.  Return values should be distributed
+  // over the entire range [0, numeric_limits<size_t>:::max()].
+
+  // _H2: the range-hashing function (in the terminology of Tavori and
+  // Dreizin).  A binary function object whose argument types and result
+  // type are all size_t.  Given arguments r and N, the return value is
+  // in the range [0, N).
+
+  // _Hash: the ranged hash function (Tavori and Dreizin). A binary function
+  // whose argument types are _Key and size_t and whose result type is
+  // size_t.  Given arguments k and N, the return value is in the range
+  // [0, N).  Default: hash(k, N) = h2(h1(k), N).  If _Hash is anything other
+  // than the default, _H1 and _H2 are ignored.
+
+  // _RehashPolicy: Policy class with three members, all of which govern
+  // the bucket count. _M_next_bkt(n) returns a bucket count no smaller
+  // than n.  _M_bkt_for_elements(n) returns a bucket count appropriate
+  // for an element count of n.  _M_need_rehash(n_bkt, n_elt, n_ins)
+  // determines whether, if the current bucket count is n_bkt and the
+  // current element count is n_elt, we need to increase the bucket
+  // count.  If so, returns make_pair(true, n), where n is the new
+  // bucket count.  If not, returns make_pair(false, <anything>).
+
+  // ??? Right now it is hard-wired that the number of buckets never
+  // shrinks.  Should we allow _RehashPolicy to change that?
+
+  // __cache_hash_code: bool.  true if we store the value of the hash
+  // function along with the value.  This is a time-space tradeoff.
+  // Storing it may improve lookup speed by reducing the number of times
+  // we need to call the Equal function.
+
+  // __constant_iterators: bool.  true if iterator and const_iterator are
+  // both constant iterator types.  This is true for unordered_set and
+  // unordered_multiset, false for unordered_map and unordered_multimap.
+
+  // __unique_keys: bool.  true if the return value of _Hashtable::count(k)
+  // is always at most one, false if it may be an arbitrary number.  This
+  // true for unordered_set and unordered_map, false for unordered_multiset
+  // and unordered_multimap.

+/* If this file is compiled with threads support, it must
+       #define __GTHREADS 1
+   to indicate that threads support is present.  Also it has define
+   function
+     int __gthread_active_p ()
+   that returns 1 if thread system is active, 0 if not.
+
+   The threads interface must define the following types:
+     __gthread_key_t
+     __gthread_once_t
+     __gthread_mutex_t
+     __gthread_recursive_mutex_t
+
+   The threads interface must define the following macros:
+
+     __GTHREAD_ONCE_INIT
+     		to initialize __gthread_once_t
+     __GTHREAD_MUTEX_INIT
+     		to initialize __gthread_mutex_t to get a fast
+		non-recursive mutex.
+     __GTHREAD_MUTEX_INIT_FUNCTION
+     		some systems can't initialize a mutex without a
+		function call.  On such systems, define this to a
+		function which looks like this:
+		  void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *)
+		Don't define __GTHREAD_MUTEX_INIT in this case
+     __GTHREAD_RECURSIVE_MUTEX_INIT
+     __GTHREAD_RECURSIVE_MUTEX_INIT_FUNCTION
+     		as above, but for a recursive mutex.
+
+   The threads interface must define the following static functions:
+
+     int __gthread_once (__gthread_once_t *once, void (*func) ())
+
+     int __gthread_key_create (__gthread_key_t *keyp, void (*dtor) (void *))
+     int __gthread_key_delete (__gthread_key_t key)
+
+     void *__gthread_getspecific (__gthread_key_t key)
+     int __gthread_setspecific (__gthread_key_t key, const void *ptr)
+
+     int __gthread_mutex_destroy (__gthread_mutex_t *mutex);
+
+     int __gthread_mutex_lock (__gthread_mutex_t *mutex);
+     int __gthread_mutex_trylock (__gthread_mutex_t *mutex);
+     int __gthread_mutex_unlock (__gthread_mutex_t *mutex);
+
+     int __gthread_recursive_mutex_lock (__gthread_recursive_mutex_t *mutex);
+     int __gthread_recursive_mutex_trylock (__gthread_recursive_mutex_t *mutex);
+     int __gthread_recursive_mutex_unlock (__gthread_recursive_mutex_t *mutex);
+
+   The following are supported in POSIX threads only. They are required to
+   fix a deadlock in static initialization inside libsupc++. The header file
+   gthr-posix.h defines a symbol __GTHREAD_HAS_COND to signify that these extra
+   features are supported.
+
+   Types:
+     __gthread_cond_t
+
+   Macros:
+     __GTHREAD_COND_INIT
+     __GTHREAD_COND_INIT_FUNCTION
+
+   Interface:
+     int __gthread_cond_broadcast (__gthread_cond_t *cond);
+     int __gthread_cond_wait (__gthread_cond_t *cond, __gthread_mutex_t *mutex);
+     int __gthread_cond_wait_recursive (__gthread_cond_t *cond,
+					__gthread_recursive_mutex_t *mutex);
+
+   All functions returning int should return zero on success or the error
+   number.  If the operation is not supported, -1 is returned.
+
+   If the following are also defined, you should
+     #define __GTHREADS_CXX0X 1
+   to enable the c++0x thread library.
+
+   Types:
+     __gthread_t
+     __gthread_time_t
+
+   Interface:
+     int __gthread_create (__gthread_t *thread, void *(*func) (void*),
+                           void *args);
+     int __gthread_join (__gthread_t thread, void **value_ptr);
+     int __gthread_detach (__gthread_t thread);
+     int __gthread_equal (__gthread_t t1, __gthread_t t2);
+     __gthread_t __gthread_self (void);
+     int __gthread_yield (void);
+
+     int __gthread_mutex_timedlock (__gthread_mutex_t *m,
+                                    const __gthread_time_t *abs_timeout);
+     int __gthread_recursive_mutex_timedlock (__gthread_recursive_mutex_t *m,
+                                          const __gthread_time_t *abs_time);
+
+     int __gthread_cond_signal (__gthread_cond_t *cond);
+     int __gthread_cond_timedwait (__gthread_cond_t *cond,
+                                   __gthread_mutex_t *mutex,
+                                   const __gthread_time_t *abs_timeout);

+

+   function
+     int __gthread_active_p ()
+   that returns 1 if thread system is active, 0 if not.
+
+   The threads interface must define the following types:
+     __gthread_key_t
+     __gthread_once_t
+     __gthread_mutex_t
+     __gthread_recursive_mutex_t
+
+   The threads interface must define the following macros:
+
+     __GTHREAD_ONCE_INIT
+     		to initialize __gthread_once_t
+     __GTHREAD_MUTEX_INIT
+     		to initialize __gthread_mutex_t to get a fast
+		non-recursive mutex.
+     __GTHREAD_MUTEX_INIT_FUNCTION
+     		some systems can't initialize a mutex without a
+		function call.  On such systems, define this to a
+		function which looks like this:
+		  void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *)
+		Don't define __GTHREAD_MUTEX_INIT in this case
+     __GTHREAD_RECURSIVE_MUTEX_INIT
+     __GTHREAD_RECURSIVE_MUTEX_INIT_FUNCTION
+     		as above, but for a recursive mutex.
+
+   The threads interface must define the following static functions:
+
+     int __gthread_once (__gthread_once_t *once, void (*func) ())
+
+     int __gthread_key_create (__gthread_key_t *keyp, void (*dtor) (void *))

+     int __gthread_recursive_mutex_unlock (__gthread_recursive_mutex_t *mutex);
+
+   The following are supported in POSIX threads only. They are required to
+   fix a deadlock in static initialization inside libsupc++. The header file
+   gthr-posix.h defines a symbol __GTHREAD_HAS_COND to signify that these extra
+   features are supported.
+
+   Types:
+     __gthread_cond_t
+
+   Macros:
+     __GTHREAD_COND_INIT
+     __GTHREAD_COND_INIT_FUNCTION
+

+     int __gthread_cond_wait_recursive (__gthread_cond_t *cond,
+					__gthread_recursive_mutex_t *mutex);
+
+   All functions returning int should return zero on success or the error
+   number.  If the operation is not supported, -1 is returned.
+
+   If the following are also defined, you should
+     #define __GTHREADS_CXX0X 1
+   to enable the c++0x thread library.
+
+   Types:
+     __gthread_t

+   The following are supported in POSIX threads only. They are required to
+   fix a deadlock in static initialization inside libsupc++. The header file
+   gthr-posix.h defines a symbol __GTHREAD_HAS_COND to signify that these extra
+   features are supported.
+
+   Types:
+     __gthread_cond_t
+
+   Macros:
+     __GTHREAD_COND_INIT
+     __GTHREAD_COND_INIT_FUNCTION

+     int __gthread_cond_wait_recursive (__gthread_cond_t *cond,
+					__gthread_recursive_mutex_t *mutex);
+
+   All functions returning int should return zero on success or the error
+   number.  If the operation is not supported, -1 is returned.
+
+   If the following are also defined, you should
+     #define __GTHREADS_CXX0X 1
+   to enable the c++0x thread library.
+
+   Types:
+     __gthread_t
+     __gthread_time_t

+/* If this file is compiled with threads support, it must
+       #define __GTHREADS 1
+   to indicate that threads support is present.  Also it has define
+   function
+     int __gthread_active_p ()
+   that returns 1 if thread system is active, 0 if not.
+
+   The threads interface must define the following types:
+     __gthread_key_t
+     __gthread_once_t
+     __gthread_mutex_t
+     __gthread_recursive_mutex_t
+
+   The threads interface must define the following macros:
+
+     __GTHREAD_ONCE_INIT
+     		to initialize __gthread_once_t
+     __GTHREAD_MUTEX_INIT
+     		to initialize __gthread_mutex_t to get a fast
+		non-recursive mutex.
+     __GTHREAD_MUTEX_INIT_FUNCTION
+     		some systems can't initialize a mutex without a
+		function call.  On such systems, define this to a
+		function which looks like this:
+		  void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *)
+		Don't define __GTHREAD_MUTEX_INIT in this case
+     __GTHREAD_RECURSIVE_MUTEX_INIT
+     __GTHREAD_RECURSIVE_MUTEX_INIT_FUNCTION
+     		as above, but for a recursive mutex.
+
+   The threads interface must define the following static functions:
+
+     int __gthread_once (__gthread_once_t *once, void (*func) ())
+
+     int __gthread_key_create (__gthread_key_t *keyp, void (*dtor) (void *))
+     int __gthread_key_delete (__gthread_key_t key)
+
+     void *__gthread_getspecific (__gthread_key_t key)
+     int __gthread_setspecific (__gthread_key_t key, const void *ptr)
+
+     int __gthread_mutex_destroy (__gthread_mutex_t *mutex);
+
+     int __gthread_mutex_lock (__gthread_mutex_t *mutex);
+     int __gthread_mutex_trylock (__gthread_mutex_t *mutex);
+     int __gthread_mutex_unlock (__gthread_mutex_t *mutex);
+
+     int __gthread_recursive_mutex_lock (__gthread_recursive_mutex_t *mutex);
+     int __gthread_recursive_mutex_trylock (__gthread_recursive_mutex_t *mutex);
+     int __gthread_recursive_mutex_unlock (__gthread_recursive_mutex_t *mutex);
+
+   The following are supported in POSIX threads only. They are required to
+   fix a deadlock in static initialization inside libsupc++. The header file
+   gthr-posix.h defines a symbol __GTHREAD_HAS_COND to signify that these extra
+   features are supported.
+
+   Types:
+     __gthread_cond_t
+
+   Macros:
+     __GTHREAD_COND_INIT
+     __GTHREAD_COND_INIT_FUNCTION
+
+   Interface:
+     int __gthread_cond_broadcast (__gthread_cond_t *cond);
+     int __gthread_cond_wait (__gthread_cond_t *cond, __gthread_mutex_t *mutex);
+     int __gthread_cond_wait_recursive (__gthread_cond_t *cond,
+					__gthread_recursive_mutex_t *mutex);
+
+   All functions returning int should return zero on success or the error
+   number.  If the operation is not supported, -1 is returned.
+
+   If the following are also defined, you should
+     #define __GTHREADS_CXX0X 1
+   to enable the c++0x thread library.
+
+   Types:
+     __gthread_t
+     __gthread_time_t
+
+   Interface:
+     int __gthread_create (__gthread_t *thread, void *(*func) (void*),
+                           void *args);
