ISTM that the right behavior would be for cygwin to build a UNIX-ish (un)zip
and for mingw to build a Windows style program.  As already pointed out
cygwin should be thought of as "Unix on Win" and IMO mingw should be thought
of as "as a free alternative for a good Win32 compiler". 

I realize that cygwin and mingw are both supported by the same compiler, but
supplying -mno-cygwin causes gcc to switch from cygwin to mingw behavior and
__MINGW32__ becomes defined.

This may be more a question for cygwin-developers, but I hate crossposts and
know most readers of that list at least review this one.  So, wouldn't it be
appropriate when compiling without -mno-cygwin for the specs file to define
"unix", "UNIX" and similar "standard" defines?  They seem to be checked for
in newlib, zlib, X11, and many other sources?

Yes I know I can make this change in my local sources, but I prefer to work
with standard sources and now seemed a good time to bring it up.  I have
been wondering about it for some time.
