Is there a "standard" -- or optimal -- way to determine at compile time
whether one is on a BSD or AT&T (Ver7, SysIII, SysV) system?
This is the best I've been able to come up with so far:

#include <stat.h>

#if defined(S_ISOCK)

/* BSD stuff */

#else

/* AT&T stuff */

#endif


Anyone have a better way?
