I think we should offer a separate Mac build just for 10.6
(much like we do for the 32-bit PPC option for 10.5).
Otherwise, were trapped in an old world and using the same
reasoning as companies that still mandate Internet Explorer 6;
forgoing the benefits of newer browsers just to make sure
a few pieces of legacy code can be supported.

That is an excellent reason for us to move as well.
Otherwise, we risk getting out of sync with the rest of the ecosystem.

One thing that can be done is to take advantage of the 3.4 alphas
and betas to experiment with having both a legacy version and
fresh build with better tools. That would let us find out early whether
the worries and fears are real and will manifest themselves in practice.
I've been building under GCC 4.8.1 for months and have encountered
no problems at all with the popular third-party modules or with linking
to existing SO files.
