Hmm, I have no access to a 32-bit machine right now, but I am running
GCC 3.4.2 on SPARC and sizeof(temp) gives 16 as expected.
One thing a could think of is that on 32-bit machines it makes no
sense to pad to 16 bytes since the natural word size (size of internal
registers) is 4 bytes resulting in an unnecessary read operation to
fetch the rest of the structure that is useless anyway.

PS: I am going to investigate this issue when I return to my lab and
will mail you the results privately if you don't mind.
