Well, we use a lowest common denominator box to build our binaries;
this enables us to ship a single binary that runs everywhere
(or everywhere we've found).  And gcc 2.95 is part of that.

My opinion is that, if it's not hard for us to maintain compatibility,
we should.

At least until we upgrade our build box <grin>.

Cheers,
