creating dependencies with gcc

[cppaddict]

When creating Makefiles, it's common to use 

gcc -M <filenames>

to produce the dependency files that will be included in your
Makefile.  Unfortunately, the output includes ALL dependencies, even
dependencies on stable system files, which need not be included.

Is there a way to tell gcc not to include those stable system
dependencies?

Is there a better alternative to gcc for creating dependency files?

Thanks for any thoughts,
