Looking at gcc-2.8.1, I see that it was added in 1990 by rms for the tahoe
port.  The tahoe port was deleted 29 days ago, so there are no longer any
users of this __shtab array.  It probably shouldn't have been in libgcc2.c
anyways, since it was only there for the tahoe port, but back then we didn't
really have machine dependent hooks to add stuff to libgcc.a.

__shtab should definitely be dropped.

When the egcs project started, there was a decision to drop all old ChangeLog
files to save space.  So if you want to look up some gcc history, you need
to have a copy of gcc-2.8.1 handy.
