If you indeed run "gcc -MM" (without any other switches), GCC should
have complained about <tmp.h> not found anywhere in the include path.
So something is missing in your description.

FWIW, GCC 2.95.3 correctly reports the dependencies: if I use -I. -MM
and <tmp.h>, it doesn't mention any headers except djgpp.ver, and if I
use -MM alone and change tmp.c to include "tmp.h", it reports all of
tmp.h, tmp2.h, and tmp3.h.  I don't have GCC 3.0.3 installed where I
type this to test that version.
