- /* 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. Pseudo-version: 1.1 */
