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.

ChangeLog

2012-07-05  Kai Tietz

	PR bootstrap/52947
	* 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
