/* 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
