This won't work (unless the DOS/Windows version of gnu make behaves
differently to Unix make).  Each command in a makefile is executed in a
separate sub-shell, so "cd" changes the directory in the sub-shell, which
then exits, but the parent process is still in the same directory.

To use "cd", you'd have to do it like this:

	cd obj;cd mingw32;echo // no MMX > mmx.h

But simply doubling the backslashes should work (though I don't have DOS or
Windows here to test it on):

	echo // no MMX > obj\\mingw32\\mmx.h
