http://www.whatis.com/posix.htm ? ;)

take a look how i.e. tcl
( http://dev.scriptics.com/software/tcltk/platforms.html ) does it?

I agree.  BTW, -Dunix is a problem with the runtime code.  Someone included a
variable named 'unix'.

Only a __linux, but I have no personal desire to add it.  IMO it just
specifies a the variant of UNIX and cygwin is not Linux, although I realize
there is a desire to be as Linux-like as possible.

Good pieces of information, however, I don't see a list of predefined macros
that identify a "UNIX" system as would be attainable by doing

touch empty.c
gcc -c empty.c -E -dM 

on a unix system.

Hmm...  I just tried this on HPUX with a self built gcc and I get unix, __unix
and __unix__.  Now this is what I was after.  Those who have linux running, is
there anything else of interest?

That't why I quoted "standard".  AFAIK there are no standards for defines to
indicate that a program is being built on a UN*X system.  I have just
noticed over the years that many packages use UNIX, unix, or some
permutation with underscores to check for a UN*X operating system.
