Hi,
I was experimenting with building gambit with Visual Studio 2012 Express and managed to create libgambc.lib, gsi.exe and gsc.exe by patching misc/vc2008. The patched version is attached. The gsi.exe starts and seems to work but I did no further tests (sadly I don't have the time right now). Nevertheless this might be useful for somebody else.
Gambit looks great and thanks to everyone who works on it.
Best regards,
Karl
