The Windows builds have always used *both* Cygwin and MSVC; Cygwin for the make and other Unix-based file tools (cp, rm, awk, sed, etc), and MSVC for the actual compilation of C/C++ code. (Prior to a few years ago, in fact, it wasn't even Cygwin, it was using MKS, a commercial Unix toolchain for Windows.)
My proposal was to move away from the commercial version of MSVC (Visual Studio 2003 and/or Microsoft Visual C++ 6.x are the currently-supported versions of MSVC for building the JDK on Windows) and start using the free version of MSVC (Visual C++ 2008 Express), before attempting moving away from MSVC entirely and using MinGW32's gcc (which is much closer to the underlying OS than Cygwin is).
I'm confident step 1 can happen. I'm reasonably confident #2 can happen. I have no idea of step #3 is even remotely possible, but figure it's worth the look, if the time is there.
