Well, the reason it doesn't exist today is that noone has worked on it.

I sorta agree, but not entirely.  In particular, I think that it's
reasonable for LLVM as a whole to require cygwin.  However, I think that
it would be great (and doable) to be able build the LLVM tools WITHOUT
linking to the cygwin DLL or using any of the emulation code.  This should
provide fast executables without having to change all of our support
makefiles and other stuff.

I really am not sure whether it would make sense to do the full VS project
thing.  In particular, it would be hard to maintain.  Porting lib/System
to use native win32 sounds like an excellent idea though, and IS quite
useful.

Thoughts?
