As thc was stated to use mingw for Windows support, it would seem that
it should work with the mingw cross compilers, although uwin was
recommended. If you want native cygwin, or even if the purpose is only
to gain a more recent version of g++ cross compiler (without all the
language support of the cross compilers on the cygwin install menu) it
seems you should consider whether the gain is worth the effort, when
your original question was how to get a gfortran for Windows.
