That is exactly true. If you want to force 32-bit executables, you can  
give the -m32 flag (similarly, there is a -m64 flag for 64-bit).

However, you can't just special-case snow leopard, because there is a  
number of 32-bit intel macs, on which you can install snow leopard,  
which themselves will default to 32-bit executables!

The only (sane) method I've found to solve this is to do one of two  
things.

1) Just use the system setting.
2) Explicitly specify -m32 and -m64 on all systems.
