When using -M, the gnu C preprocessor will repeat occurances of included
files. This is commonly occurs in G++, where the ``#ifdef foo #define foo...''
convention is used.

It's not a major hassle, it just slows down makes and causes the makefile
dependency information to be much larger than necessary.
