I cannot reproduce this problem: "gcc -MM" works for me as expected in
this case.

Is it possible that you edited the file longfilename.h with some
Windows editor?  In that case, GCC cannot find longfilename.h because
the short 8+3 alias of longfilename.h is something like longfi~1.h
instead of longfile.h.  You need to use a DOS or DJGPP program to
create longfilename.h on NT, and then it will work.

Alternatively, you could install the LFN driver for NT, see section
3.3 of the FAQ for details.
