I think it should work. Are you saying that gcc/config/i386/x-mingw32 
contains the text given in the above message, and xmake_file is set in 
config.gcc?

No, it is checking whether the "build" environment differs from the "host", 
which are both mingw32 here. As a wild guess perhaps you could override this 
by putting "STMP_FIXINC=" in the host makefile fragment x-mingw32.

I don't know where you could find this information :(.
