No -- `file` used to give the name of the prog. that dumped
the core file. Since the switchover to elf, it's output was changed
to the garbage^h^h^h^h^h^h^h useless info line you see above. This has
been irritating me for a long time -- I would *love* to see the old
functionality put back in.


ps - As for gdb, I could tell you more if I could get it to compile
on the sparc/solaris machine at work(at least then I could
use it -- guess I'll stick with printf for now...).
