First, please read Apple technote 2137:

Also good:

Basically, the idea is that one executable file contains the object code
for both ppc and intel.  And the compiler can make such a 'universal
binary' on either a ppc mac or intel mac.  As such, it is important to
_not_ assume that the properties of the build machine match the
properties you are building for.  Things like the endianess, structure
padding, sizeof(int) etc.  Just because I'm building on a big endian ppc
does not mean I'm building _for_ a big endian ppc.
