Hi Claus, I was reading your instructions on the GHC wiki page, http://hackage.haskell.org/trac/ghc/wiki/Building/Windows, and they are wonderful - exactly what I wanted. However, they don't work. When downloading Cygwin you are told to add haskell.org/ghc/cygwin as a path so it can pick up the setup.ini file. However, in the latest version of Cygwin it obvious wants signatures for all the .ini files: --------------------------- Cygwin Setup --------------------------- Unable to get http://www.haskell.org/ghc/cygwin/setup.ini.sig from http://www.haskell.org/ghc/cygwin --------------------------- OK --------------------------- Could someone please add the appropriate signature file?
