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

[Johan Tibell]

I've merged and pushed the changes to the "stable" branch on GitHub. If
someone could verify that it works fine on Windows, I'll make another
release.

In addition to running whatever program you're interested in, also run:

cabal clean
autoreconf
cabal configure --enable-tests
cabal build
cabal test

All tests should pass.
