I see no problem in cygwin32 specs defining "unix", but I have yet to
see a good argument for getting rid of _WIN32 from x86-win32 targets,
especially from mingw32.

So far I've seen only a 2 or 3 posts suggesting we get rid of WIN32 
(Earnie Boyd and someone else -- Larry Hall? Sorry, I can't remember), 
but all of these were low on details as to why. If I'm missing a few 
posts that you believe are pertinent, please feel free to shout.

Granted that lots of code out there IMO incorrectly uses _WIN32 where it
should be using _MSC_VER or BORLANDC or, better yet, autoconf style macros 
(or some other similar mechanism) to define capabilities of host/target 
system; I think over time we should be getting those packages fixed instead 
of getting rid of WIN32 and temporarily masking the problem.
