Although not really answering your question consider using the value.  I do
the following in my chat program.  (I use RCS but the idea is the same.)
every source file has a line such as the following:

char chat_rcsid[] = "$Id:$\b ";

where 'chat' is replaced by the current module name such as chatter_rcsid,
chc_rcsid and chs_rcsid.  I then declare these as extern in one module and
print them when given an undocumented command with the following:

    printf("%s\n", chat_rcsid + 1);

For each string.  Makes a good debugging tool especially if someone else
compiles the program.
