Does anyone know of a decent C cross-referencer around?  cxref is almost
completely hopeless for my sort of program (10-20K of X code, heaven help
me!)  What I want are the following semantics:  

    Complete cross-references for all symbols that are defined in one of
    the files specified on the command line, which are visible outside the
    file in which they are defined.  I would prefer to be told about both
    pre-processor and compiler symbols.

I can live with having to do some post-processing, but I am not going to
parse C (so pre-processing is out)!  I can also live with being told just
about compiler symbols (i.e. the state after cpp), and with being told
about all symbols visible outside their function.  Unfortunately, I cannot
see how to do any of this with any reasonable combination of existing UNIX
utilities.

Please reply by EMAIL, if possible.
