The -mno-cygwin has been dead for a few several years now.  The option
is no longer available in current GCC.  You now install the
{x86_64,i686}-w64-mingw32 cross compilers and specify
--host={x86_64,i686}-w64-mingw32 when you configure.

So to get Cygwin specific build you just don't specify the --host option.

The change to configure.ac and supporting .m4 files is up to you.  But
-mno-cygwin isn't available if you plan to use current GCC regardless.
