alignment of Int with size 4 is 4
alignment of Short with size 2 is 2
alignment of Double with size 8 is 4
alignment of LongLong with size 8 is 4
alignment of Float with size 4 is 4
alignment of Char with size 1 is 1

looks like the packing is dependent upon the arg size if i read this 
right.  i am not that conversant with c (i program in Ada) but if i 
read this right, char is not padded at all, short is padded with one 
byte, and both long and longlong with 3. am i reading this correctly?

#define ALIGNMENT_OF_SIZE(S)    (((S>1)?2:1))
is what is defined for 68k which is obviously not correct for this 
result.  can ou give me a macro that works for this result? thanks 
for any insight.

best jim

At a recent computer software engineering course in the US, the participants
were given an awkward question to answer.  "If you had just boarded an
airliner and discovered that your team of programmers had been responsible
for the flight control software, how many of you would disembark
