| # On some hosts (e.g., HP-UX 10.20, SunOS 4.1.4, Solaris 2.5.1), mkstemp has a |
| # silly limit that it can create no more than 26 files from a given template. |
| # Other systems lack mkstemp altogether. |
| # On OSF1/Tru64 V4.0F, the system-provided mkstemp function can create |
| # only 32 files per process. |
| # On systems like the above, arrange to use the replacement function. |
