Wholly support moving OSX to x64. x86 should be supported only on a
best effort basis for legacy.

Doesn't 10.5.x have the ability to generate and run 64-bit binaries?

That sounds reasonable to me. The big caveat is that OSX >= 10.5.8 && < 10.6 should still be targeted as well. While non-x86_64 Macs are quite old, OSX 10.6 is still pretty new and so there are a lot of people still using 10.5 (and our department still has a couple boxes running 10.4).
So even though 10.5.8 defaults to 32-bit, it should still be actively supported (as an x86_64 architecture). Just pass the necessary flags to gcc :)
It would be really nice for x86 mode to be well supported for a while longer.
Yes, it'd be really nice to support 32-bit mode for a while yet, even if it isn't actively being targeted for improvements.
