i was looking for an a definition of acid(1)'s integer but i
must have missed it. i had always assumed that they were
intended to be unsigned. evidently there is some signed
arithmetic going on, and this is calculations are subject to
the local compiler's rounding rules. i suppose this is correct
if acid integers are supposed to be signed.
so the question is: are they?

plan 9:
acid: 0xffffffff * 0xffffffff
0xfffffffe00000001
p9p:
acid; 0xffffffff * 0xffffffff
0xffffffff * 0xffffffff
0x00000001
just to make sure this isn't a printing issue
acid; x = 0xffffffff * 0xffffffff
acid; x==1
