Yes, I'm sorry for not qualifying that statement: gcc 3.3 ports has poor
amd64 support.  The gcc 3.3 in core FreeBSD has been modified by the
persons mentioned so that it is very stable on amd64.

As you say, gcc 3.4 has much better amd64 support and closer ANSI
compliance.  Because of this, I have found a few packages in ports that
will not compile with the gcc 3.4 port (CC=gcc34, CXX=g++34).  These
tend to be trivial fixes.  The only concern I have is that gcc 3.4
produced a non-working openldap-sasl-server-2.1.30.  The compiler in
core -CURRENT made a functional one.

Cheers,
Sean
