I just tried a small experiment and it looks like it should work.

On cygwin
	$ mount
	C:\cygwin\lib	/usr/lib	system	textmode

I run gcc -dumpspecs

On win32

	mkdir \usr\lib

Copy \cygwin\lib\* to \usr\lib\*

copy gcc.exe and cygwin1.dll to \usr
cd \usr and run gcc -dumpspecs. This is the same as above. I suspect that
if you put all (whatever that means) your files under \usr you'll be
fine. You'll only have the problem that the drive won't be included in
the path.
