It is not available until OS X 10.5. (The part "Only applies to Mac OS X 10.4 and later." is incorrect.)
If you don't have access to 10.5 seeds, just ignore it for now.
If you do have 10.5 access, the 2006 WWDC talks have lots of info on this for you.

I found this in building options. But I search in the documents online, nothing useful found.Only info is from the xcode interface, saying:

Compiles and marks code as using assignment primitives within the Objective-C runtime; tools and applications compiled with this option will run with a garbage collector and will require that all other Objective-C code be also so compiled. Only applies to Mac OS X 10.4 and later. [GCC_ENABLE_OBJC_GC, -fobjc-gc]

I'm still feeling confused, does this option has something to do with the "retain-release" mechanism, or it is doing something else, I noticed that this option is originally disabled, is it partially because of the cost of overhaed?

Thanks for helping my dummy questions...

Jay
