: Just to make sure we are agreeing on the same thing, can you restate the

Briefly:

#if (defined(unix) || defined(__unix__)) && !defined(USG)
#include <sys/param.h>
#endif

...

#if defined(BSD) && BSD >= 199304
blah
#endif

This casts a wide enough net to include almost all systems that have a
sys/param.h that is likely to define BSD, yet specifically excludes
things that don't work (eg WinNT and old SYS V (pre r4) and SYS III
machines).

While I haven't seen the final text, this is what is currently in the
handbook until we can refine it to be something even better.
