[Bug tree-optimization/31602] Overflow warning causes GDB -Werror build failure

Yes, the warning is happening because gcc relies on undefined signed overflow
when assuming that it will execute the loop at least once.  Of course when
using -fwrapv the loop should not be executed at all when num > INT_MAX - 10.

I'll try to figure out what to do about this.
