Following various discussions about porting software to A/UX I have
the impression that nobody ever took the time to read the man-page of cc(1)
to the end. You should all do that (there is other interesting stuff in
there).

NO! Your not supposed to define that youself! Why do you think that
Apple was so nasty to put those annoying underscores in front of the
defines ?

What you should do instead is using the '-Z' flag of cc. (Ok, you'll have
to read until page 4 of manual to find that...:-) :-)

Here ist the relevant part (not all options shown):
----
	  -Zflags Special flags to override the default behavior (see
		  NOTES in this section).  Currently recognized flags
		  are:
                  S    Compile to be SVID-compatible.  Link the pro-
		       gram with a library module that calls
		       setcompat(2) with the COMPAT_SVID flag set.
		       Define only the SYSV_SOURCE feature test macro.

                  P    Compile for the POSIX environment.  Link the
		       program with a library module that calls
		       setcompat(2) with the COMPAT_POSIX flag set.
		       Define only the POSIX_SOURCE feature test mac-
		       ro.

		  B    Compile to be BSD-compatible.  Link the program
		       with a library module that calls setcompat(2)
		       with the COMPAT_BSD flag set.  Define only the
		       BSD_SOURCE feature test macro.
----

This will not only set the proper define for the preprocessor but also
link your program with the right compatibility library from /lib automaticly.
So you should also remove any -lbsd -lposix or -lsvid options.
