   i think that only works for x86.  It would not work in the most general case.  For example,
an 8-bit processor which has all of the data on a byte-aligned, 8-bit wide stack.  in would
be 16-bits (2 bytes) and long 32-bits (4 bytes).  That would screw up the stack/parameter
alignement in that case.
