Log:
Revert ABI breakage in libsupc++.
Unfortunately, the ABI was broken upstream for the 4.2 release, which we
imported. We then shipped the broken version for several years and certain
ports (e.g. libobjc2) depend on it, so we're stuck with it for now...
We should revisit this for 10.0, since we're allowed to break the ABI then,
but
until then we should keep the ABI we shipped with 8.x and 9.x.

Let me try to recap:
gcc-4.2.1 broke the ABI and we shipped it for a long time.
The bug was detected by Apple and others:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35081
It was fixed for gcc-4.2.2 (which we didn't ship):
http://gcc.gnu.org/viewcvs?view=revision&revision=129061
<http://gcc.gnu.org/viewcvs?view=revision&revision=129061>
I inadvertently fixed the bug 3 months ago when I brought in the
last LGPLv2 updates for libstdc++:
http://svnweb.freebsd.org/base?view=revision&revision=228780
<http://svnweb.freebsd.org/base?view=revision&revision=228780>
The fix hasn't been shipped but was MFC'd and is actually
in 8.3-RC* !!
David's commit actually restores the gcc 4.2.1 bug (?).
Pedro.
