Often such unused variables are named ``rcsid'' or ``sccsid'', etc.,
in which case there *is* a reason for including them in the object
file.

Have a look in the file toplev.c, around the middle (roughly lines 1800-2200),
there are some comments about this sort of thing, and also about unused
static functions, etc.
