Most of these files are duplicates or kind of empty or some such. A little
more flexibility would be nice. There are also a couple of subtle
technical problems with AC_LINK_FILES in Autoconf which would lead me to
suggest that, "Given a tie, don't do it."

Why not

ipc.c:

#ifdef __BEOS__
/* BEOS stuff */
#elif defined(__FOONIX__)
/* FooNix stuff */
#else
/* "normal" stuff */
#endif
/* common stuff */

i.e., everything in one file but separated by system. That would also
eliminate the need for duplicating stuff that could be used across the
board.

In practice people also do error message rephrasing, include file
cleanups, function prototype changes, add or remove global variables,
change defines to enums, update comments, etc. There are also a couple of
things in ipc.c that are common to all implementations, so those would be
just waiting to fall out of sync.

I've seen stuff getting out of whack with reality in the *same* file
because it was #ifdef EXOTIC_FEATURE, so I'd agree with Tom to keep things
"in sight" as much as possible.

If everyone got "frustrated" if people offer ideas then we'd never get
anywhere. *shrug*
