Done in rev 51711 on the 2.5 branch.
Done in rev 51715 on the 2.4 branch.
Done in rev 51716 on the trunk, although in the LONG_MIN way (which is
less obscure, but a more "radical" code change).
I don't care about the 2.3 branch, so leaving that to someone who
does. Merge rev 51711 from the 2.5 branch. It will generate a
conflict on Misc/NEWS. Easiest to revert Misc/NEWS then and just
copy/paste the little blurb from 2.5 news at the appropriate place:
- Overflow checking code in integer division ran afoul of new gcc
optimizations. Changed to be more standard-conforming.
