MinGW compilation on Windows

I have a bunch of patches that I'd like to submit to enable XEmacs to be compiled by a native MinGW gcc (rather than Cygwin's cross-compiler gcc -mno-cygwin). A MinGW installation gcc (www.mingw.org) requires different include paths than gcc -mno-cygwin. There are also some #defines in the wrong places and some typedefs that need to be altered. Comparing the preprocessor directives defined by MinGW's Windows native gcc, and the ones defined by Cygwin's gcc -mno-cygwin, the only difference is that __MINGW__ is merely defined -D__MINGW__ by cygwin, whereas in mingw gcc, it's defined -D__MINGW__=1.0. Would it be a bad thing to add in a new #define to XEmacs that would discriminate between these two compilers, and then modify the places in the code (and configure script) that care about the difference to get the differences right? It would enable me to get rid of a whole load of patches I apply to each new XEmacs release to make it compile correctly under MinGW. What do you think?
