[web-devel] [Haskell-cafe] network-2.3.0.10 compiled for ghc 7.4.1 windows

[Alberto G. Corona]

I switched to Git bash and the runtime error produced by the library
is the same.
This error may be produced because  the configuration it does not
detect the netwiorkin related includes such is socket.h. This does not
exist neither in the ghc installation neither in GIT/Mingw
