Using configure.bat is currently the only way to build the native
Windows Emacs.

Yes, I know.  If that's the only problem with using Cygwin tools to
build a native Windows binary, making the change is very easy.

We could support that option (as well as using MSYS tools with MinGW
compiler), if someone did the job of adapting the configury.
