Some cygwin/mingw related things

[Sigbjorn Finne]

The --with-gcc= option isn't understood by the ghc/configure
script -- or any other of the configure scripts kicking around,
I would imagine -- hence ignored.

Save yourself all this bother by putting mingw/bin to the front
of your PATH (it's the right thing to do, anyway), or prefix
a CC setting before invoking the configure script:

   foo$ CC=/ming/bin/gcc ./configure <....>

--sigbjorn
