I have been able to get this working fairly smoothly. Setup is a bit of
a pain. It seems that the cygwin support for the -mno-cygwin option is a
bit half-hearted, particularly when it comes to c++.

General outline of how to get this working:
(1) normal cygwin install (setup.exe)
(2) download & untar latest mingw package
(3) run a g++ compile with -mno-cgwin -v options & look at where the
compiler & linker are searching for headers & libraries (I suppose you
could go straight to the specs file for this information, as well.
(4) now comes the tricky part -- either copy, or (perhaps better) link
the include & lib directories from the mingw distribution into cygwin's
/usr/include/mingw & /usr/lib/mingw directories. Pay particular
attention to the subdirs for the g++ std library.

Now when you use -mno-cygwin you're essentially running a cross-compiler
hosted on cygwin, targeting mingw. I would think this would be a very,
very popular option under cygwin. You have benefit of the full gnu
toolset for development, and end up with windows-native executables, at
a significant discount to what VC++ would cost ;-)  My question is, why
doesn't cygwin setup do all of this for you? Maybe what is needed is a
cygwin "package" for the mingw-cross?
