Not true, boost::int32_t is a 32-bit integer type, *exactly* 32-bits wide. 
The boost::int_least32_t types may be wider than 32-bits, and may be what 
you were thinking of.

However just because two types are both 32-bits wide, doesn't mean they have 
the same byte order.

So still back to square one, but for a different reason.  Well OK a 32-bit 
binary int would be portable between IA32 and IA32EM64, but not to IA64.
