Hello,
This patch fixes an long outstanding bootstrap-issue for mingw-native
targets by using msys' make.
The problem is that this make *auto-magical* modifies POSIX-paths to
DOS-style paths. This leads to
the issue that two DOS-style paths getting merged together for native build.
This patch simply makes sure that the definition of
NATIVE_SYSTEM_HEADER_DIR remains a POSIX-style
path.

* config/i386/mingw32.h (NATIVE_SYSTEM_HEADER_DIR): Define it always
as "/mingw/include".
Tested for x86_64-w64-mingw32 by Rainer. I will apply this patch
tomorrow, if there aren't any objections by other windows maintainers.
Regards,
Kai
