Agreed. It seems like most setups get upgraded within 6 months or a year of the next release. So phasing out along that sort of time frame makes sense.

Right now things will build all the way back to 10.4 - although I'm not suggesting we need to support that forever - but I think it unreasonable to expect everyone to use Mountain Lion, for example. Snow Leopard is still at gcc 4.2, and a lot of people (even in the Sali lab) still use that.
Just to add an *, it is a heavily modified gcc 4.2, I think (Mountain Lion's gcc is also 4.2).
I'm not saying we drop old versions immediately (nor that we go and break backwards compatibility out of spite :-).
