Log Message:
Add a few casts to avoid (IMHO bogus) gcc warnings breaking the vax build.
- if (dayoff < min_time / SECSPERDAY) {
+ if (dayoff < (long)(min_time / SECSPERDAY)) {
time_t and zic_t are 64 bit types, and max_time and min_time
are the largest possible positive and negative 64-bit values.
max_time / SECSPERDAY or min_time / SECSPERDAY will be much too
large to fit in a 32-bit int, and casting to int will cause overflow.
Does adding a /*CONSTCOND*/ comment work? If so, I'd prefer that
to a cast. If you do need a cast, then I think you should cast
dayoff to zic_t.
