| /* generic.h -- anything you don't #undef at the end remains in effect. |
| The ONLY things that go in here are generic indicator flags; it's up |
| to your programs to declare and call things based on those flags. |
| |
| You should only need to make changes via a minimal system-specific section |
| at the end of this file. To build a new section, rip through this and |
| check everything it mentions on your platform, and #undef that which needs |
| it. If you generate a system-specific section you didn't find in here, |
| please mail me a copy so I can update the "master". |
| |
| I realize I'm probably inventing another pseudo-standard here, but |
| goddamnit, everybody ELSE has already, and I can't include all of their |
| hairball schemes too. HAVE_xx conforms to the gnu/autoconf usage and |
| seems to be the most common format. In fact, I dug a lot of these out |
| of autoconf and tried to common them all together using "stupidh" to |
| collect data from platforms. |
| |
| In disgust... _H* 940910, 941115, 950511. Pseudo-version: 1.3 |
| |
| Updated 951104 with many patches from netcat feedback, and properly |
| closed a lot of slop in open-ended comments: version 1.4 |
| 960217 + nextstep: version 1.5 |
