Indeed. I wouldn't like to re-implement pre-processing behavior myself.

It should (because the '#line' statements would then mention parse.cc
and not y.tab.c). OTOH, the little other patch I sent (that adds '-l' flag
to YFLAGS in Makeconf.in) also avoids the problem, because bison
does not produce '#line' statement anymore.
