Leif,
apart from rough testing . . . I don't have rights to use sst and not even
enough knowledge about RISC instructions, but maybe it could be interesting
to compare how both versions are compiled to see if there are some machine
instruction added to fix the missing semi-byte.

 It was indeed true on the CISC machines. As for RISC, it is trivial
 to make a little test program that adds up a million or a billion packed
 numbers (all with the same value, say 123) and see how long it takes.
 Try it and give something back to the community by reporting the result
