32bit-64bit

I was reading over this question and wondered if the accepted answer might also be a way to determine the architecture. For instance, in asm could I push a WORD onto the stack and then check SP. Compare the new SP to the old SP:

Diff of 4 means 32 bit
Diff of 8 means 64 bit

Am I correct in this thinking?

When I pass compiler flag "-mmacosx-version-min=10.5", what does it mean? I think it implies the result binary is x86, not ppc, but is it 32 bits or 64 bits?
