None of the configuration control packages on the market that I know
of will do this.  (However, I haven't seen DSEE for about two years.)

There was some research about this kind of thing at GTE Labs in Waltham, Ma,
described at a conference a few years ago.  This sort of thing really begins
to need a 'program informaion database', where significant results of each
compilation (possibly including, but not limited to, the parse tree) are
kept around for use by other tools.  'Keep_state' hacks are a beginning, but
to know about define usage, etc, you want to go farther.  (Once you've done
define usage, the next job is to bring up automatically into the editor
all calls of the subroutine whose calling sequence you have redefined.
This is possible with existing tools, to some extent.  So is the problem
with defines.)
