I don't think you're missing a thing and I agree with you.  It doesn't
belong in autocoonf.  This is a platform dependent issue that should be
handled in the platform dependent coding of Makefile.in and/or
configure.in.  The application maintainer/porter knows that the -mwin32
switch is needed and can make certain it gets added to CC or CFLAGS and
CXXFLAGS under the appropriate conditions.

I can't even understand how such a macro fits Autoconf.  I may need it
and I may not need it but Autoconf can't determine my needs it can only
determine what I have.

Earnie.
