Try the "C cross-referenence database system" submitted by Greg McGary
(sun!suneast!kumquat!gmcgary).  His description of the package follows:

     This  is  a  program  identifier database  package.  These  tools
     provide a logical  extension to ctags. (which is  limited in that
     it only stores the location  of function and type *definitions*).
     The ID facility stores the locations for all uses of identifiers,
     pre-processor names, and numbers (in  decimal, octal or hex). The
     id-database is  most useful  for maintaining large  programs that
     consist  of many  source  files.  The database  is  simply a  two
     dimensional   boolean  array   indexed  by   identifier-name  and
     source-file-name. For a given  identifier and source-file, if the
     identifier occurs  in the  file, the boolean  value is  TRUE. The
     database may be queried either by identifier-name or file-name.

If you're planning on running this on a 16 bit machine, you will have to
make some extensive modifications.  The code expects you to have 32 bit
integers (it does malloc's on longs, and lseek's with integers).  I have
it working reasonably well on my AT and if necessary I can mail you my
changes ...
