Build fix for expat 1.95

[Daniel Jacobowitz <drow@false.org>]

RHEL3 ships with a version of expat which is almost, but not quite, good
enough.  And the configure script picks it up as OK.  Rather than making
the configure script pickier, I made GDB less picky; the only problem are
some missing constants.  Non-zero for success, yuck.

Checked in.
