What your describing is what I've heard called a "cross reference
generator" program.  The cygnus folks have a C++ source code analyzer
that does this (and more, apprently) and they have added some small
hooks to gcc in order to gather the necessary data.  I don't think
those hooks are enabled by default.  Cygnus only makes the source
available on some CD you buy from them, I think.  This particular
variation of gcc isn't completely available by FTP.
