Outside prc-tools, the only other Cygwin tools used by the new developer suite are GNU make and sed. I know GNU make and GNU sed are supported by MinGW. However, even if prc-tools was ported to use that library, that wouldn't really affect much. Both Cygwin and MinGW make choices that change the Win32 way-of-doing-things into something that looks more Unix-like.
PODS also uses gcc and gdb for x86 development and debugging, required for creating Protein applications running in Palm OS(R) Cobalt Simulator. And then there are the host of binutils that gcc and gdb rely on.
