[Bug c/30477] Integer Overflow detection code optimised away, -fwrapv broken

[pinskia at gcc dot gnu dot org]

Fixed in 4.0.0, 3.4.x is no longer being maintained by the FSF and has not for
a while now.

If you want to figure out how which patch fixed it in 4.0.0, you can do that by
doing a binary regression search on the source.  There has been so many patches
between 3.4.x and 4.0.x it is hard to keep track of each one.

If you don't want to move to a newer GCC, that is your issue.  Any GCC before
3.3 does not even have -fwrapv so providing all the fixes in one patch is hard
because  options handling has changed a couple of time, fold-const.c changed a
lot, etc.
