So "gcc -mno-cygwin" does, as well as any other Cygwin application which
accepts

c:/cygwin/usr/local/test.c
c:\cygwin\usr\local\test.c
/cygdrive/c/cygwin/usr/local/test.c
/usr/local/test.c

A bit more flexible than Mingw, isn't it? :-)

Again, what is the problem with "gcc -mno-cygwin", if mingw-build C++
libraries are supplied?

You have not convinced me that you *really* need Mingw-build gcc.

You needn't. All paths that Mingw-build gcc accepts is also acceptable for
Cygwin-build gcc (no matter is -mno-cygwin flag used or not). As for your
application sources (XEmacs or whatever), they should *not* rely on the
place where the system include files resides. If they do, it's very bad
programming style, if not to say more ...

Hope to hear from you soon,
Dmitry
