The attached code is OK with gcc 3.3.6 debian and gcc 4.0 without -O2 but does

GCC does not have a proper modulo overflow semantics for signed
integral types.
1. The loop optimizer seems to assume that signed overflow does
not happen (or is undefined).
2. On x86 INT_MAX/-1 seems to trap (instead of implementing
modulo semantics).
