We are looking for a tool that will allow us to scan many (very many) C
source files to determine which functions are no longer used. A very
detailed cross referencing program could probably do the job.

Any feedback would be appreciated.

[If you're compiling them on a Unix system, I've often hacked up a little
cross-referencer which uses nm, sort, and some awk scripts to produce an
xref of who calls who. Doesn't address the issue of intra-module calls,
though. I'd think that pretty much any C function cross-referencer would
be able to give you what you need. -John]
