FWIW, the most recent Cygwin snapshot (which will soon be Cygwin 1.5.19) works fairly well on Windows 64 so it is possible to have a linux-like environment on Windows 64 if someone wanted to develop there. It's probably easier to just develop on Linux using a cross compiler, though. Porting MinGW is definitely the way to go. It will be a major effort to get Cygwin working as a true 64-bit app. cgf
