The test case is included in the PR above, but it's not necessary to include this check because * the autoconf checks succeed with gcc3, it doesn't optimise them away as aggressively as recent gcc4 versions * the only way to disable it is using -O0 The idea of the PR is: there's a possibly unsafe optimsation, but we can't turn it off with -fwrapv as we're supposed to, only with using -O0, which sucks, so please fix -fwrapv.
