I've got a Cocoa program compiled using GCC3 on 10.2 with the latest

10.2-specific functionality, so I'm wondering how I can compile a
version that will run on 10.1. I don't have a machine with 10.1 to use
to test.
Does anyone know what steps can I take to produce (on 10.2) a binary
that will run on 10.1? Will switching to GCC 2.9 do it? I don't have
any frameworks linked other than Foundation and Cocoa, and am not
using any of the new features added in 10.2.
Any thoughts are appreciated. TIA.

If you set a compiler flag (in your target settings) like so:
-DMAC_OS_X_VERSION_MAX_ALLOWED=MAC_OS_X_VERSION_10_1
and recompile, you'll find out for sure what 10.2 stuff you're using.
Also, check out Apple's technote on the subject:
