I tried to do this once; maybe I'll try again when I have some free
time...

O_RDONLY is (not) coming from fcntl.h because you aren't using the flags
-D_SYSV_SOURCE and -D_BSD_SOURCE. A/UX's cc autodefines these; I think
it's braindamage and so gcc doesn't. I'm hacking together a set of
include files that don't need these defines in my nonexistant free time.

I don't have the xview2 code around at the moment; I'll bet one of the
.h files is defining USG based on the -DSYSV argument (USG is often used
as a synonym for SYSV). struct sigvec is defined in sys/signal.h; you
have to have _BSD_SOURCE defined to actually get the definition, though...
