Can you post the patches you made?

I'm not sure the -mno-cygwin flag will work on any front end besides C,
when using a build that targets cygwin. It should be pretty easy to
build a mingw target compiler, though (search the archives), and once
you have done that, you don't even need to use -mno-cygwin. If I've
been tracking archives correctly, using (build, host, target) triples,
people have built (linux, mingw, mingw), but no one has yet reported
success with (mingw, mingw, mingw) or (cygwin, mingw, mingw); or the
even cooler cross-compiler (*, cygwin, mingw).
