Provides missing Win32 API

#1windows pipe support

There seems to be no haskell library that supports Windows pipes, as documented at http://msdn.microsoft.com/en-us/library/windows/desktop/aa365137(v=vs.85).aspx

The haskell process library does have a mkAnonPipe in its cbits, that supports Windows, but it is not exported.

I think this would be a nice addition to your library. I find myself needing anonymous pipes when porting a unix program.
