[Haskell-cafe] GHCi and Cairo on Windows

[Malcolm Wallace]

On Windows, it is necessary to add to your PATH variable the bin directory where the gtk+ DLL lives.  Note, this is the C DLL, not the Haskell one produced by gtk2hs.  For instance, on my machine the relevant directory is C:\workspace\ext\gtk+-2.20\bin. It is quite likely different on yours.
