Only it strikes me that it might be plugging the wrong hole. I.e., that
the real issue is that somehow we're not including sys/wait.h in all
cases. Would it perchance also work to have
somewhere at the top of the files that use the two macros (sysutils.c
and sys-unix.c AFAICS).
"&& defined(WEXITSTATUS)" probably won't break anything that wasn't
already broken, but it does insert a default definition that could
conflict with the one intended for the OS (that's what include files and
macros are for, after all).
