I'm trying to build GHC on 64-bit Windows 7. I installed Cygwin, GHC and cloned

Preferred POSIX equivalent is: /home/tewi/head
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:

I have gcc installed under Cygwin, but for some reason ./configure is looking
for an in-tree
compiler. I tried passing --with-gcc=/usr/bin/gcc to configure but with no
result. Help?

Windows GHC *shall* use in-tree compiler. Windows GHC does *not* use
cygwin runtime at all!
Now the best way to build GHC on Windows is to use MSYS2:
https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows/MSYS2.
I'd also add that most recent versions are
http://sourceforge.net/projects/msys2/files/Base/i686/msys2-base-i686-20140216.tar.xz/download
for 32-bit windows,
and
http://sourceforge.net/projects/msys2/files/Base/x86_64/msys2-base-x86_64-20140216.tar.xz/download
for 64-bit windows.
Please, take into account this is *build environment* and in no way is
related to gcc compiler and runtime used by GHC on Windows.
Cheers,
Kyra
