Bug fix missed in gcc-2.95.3 (and gcc-2.95.2)

["Adam J. Richter" <adam at yggdrasil dot com>]

	This bug fix seems to have been missed in gcc-2.95.3.  It
was also missed in gcc-2.95.2.

	I understand there were some concerns about the correctness
of the proposed fix, but I don't know gcc well enough to understand
those concerns.  If you folks think that Mark's fix is incorrect, how
about at least putting this test case in whatever test suite you use, so
that it is not forgotten as an open bug?
