Having discussed the issue privately with Alberto, I've found another bug
and updated my pull request [1]. Using that code it should be possible to
build the network library on Windows using MSys on GHC 7.4.1.

yes i did it,.
the error is as follows:

Nothing bur a long history of failures. The problem is the
configuration and versioning of MinGW and MSys. This  is a nighmare.
