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.
