The command

	g++ -M foo1.c foo2.cc foo3.C

will give:

foo1.o: ...
foo2.o: ...
foo3.C.o: ...

This code in cccp.c supplies the make targets for g++ -M:

      /* Output P, but remove known suffixes.  */
      len = strlen (p);
      if (p[len - 2] == '.' && p[len - 1] == 'c')
	deps_output (p, len - 2);
      else if (p[len - 3] == '.'
	       && p[len - 2] == 'c'
	       && p[len - 1] == 'c')
	deps_output (p, len - 3);
      else
	deps_output (p, 0);
      /* Supply our own suffix.  */
      deps_output (".o : ", 0);
      deps_output (in_fname, 0);
      deps_output (" ", 0);


Obviously .C is not a "known suffix".  .cc has the advantage over .C
that it can be used under systems which are not case-sensitive.
