I get
XPASS: g++.other/conv5.C discarding const - (test for errors, line 6)
which, I'm guessing, is because this fixed the bug:
1998-12-16 Mark Mitchell <mark@markmitchell.com>
* class.c (resolve_address_of_overloaded_function): Do conversion
to correct type here, rather than ...
(instantiate_type): Here.
Can we get the testsuite updated?
