This is true for all modern platforms, actually. As Luigi Rizzo has 
already pointed out, on an X86 32-bit system the compiler will still 
allocate 4 bytes on the stack for a 'short' passed by value if the 
surrounding arguments have 4-byte alignment requirements. It may do so 
even then there are no alignment issues, for optimization purposes.

Of course, this make little different on platforms where there are 
adequate registers for the arguments to be passed in, since they won't 
be placed on the stack in that case.
