http://sourceforge.net/projects/msys2/ is *much* better than stock msys. I've successfully built ghc HEAD quite recently (a month ago or so) using it. Interesting! There appears to be about zero documentation, but I unpacked the tar ball (which has pre-built binaries), put it in c:/msys32, added c:/mys32/bin to my PATH, and tried. Starts well, but two problems. * I get lots of this (non-fatally): perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LC_ALL = (unset), LANG = "ENG" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). * But then I get this error which brings things to a halt: checking for gfind... no checking for find... /usr/bin/find checking for sort... /usr/bin/sort checking for GHC version date... inferred 7.7.20131001 checking for ghc... /cygdrive/c/fp/HP-2013.2.0.0/bin/ghc checking version of ghc... 7.6.3 GHC path canonicalised to: /cygdrive/c/fp/HP-2013.2.0.0/bin/ghc checking build system type...

This is very depressing. I do not know a fix. If you google around and find a fix, do tell us.
