I would like to tweak cpp to dump some usage stats from its symbol
table -- like dumping which #defines were not used at all, etc.
I'm wondering if someone can help me figure out where in the code I
would look to start to do this.
(I know that I'll need to add a command-line argument, and I'm sure I
could figure that part out.)
Thanks.

In addition to what Ian said, for this particular case, search for
warn_unused_macros in libcpp. That will show you the implementation of
a similar feature.
