gcc's defaults have changed over time.  In 10.5, it builds for 32 bit;
in 10.6 it builds for 64 bit.  This is regardless of the 'bitness' of
the kernel.

In any case, using -m32/-m64 is not customary/correct on OS X.  The
proper thing to do is specify "-arch" and the architecture you want to
build for.  Possible options are: ppc, ppc64, i386, x86_64.
