The check as Noah wrote it rejects *all* 32-bit IBM compilers, not just
buggy ones. That was okay when the effect was only a rather minor
performance loss, but refusing to build at all would raise the stakes
quite a lot. Unless you are volunteering to find out how to tell broken
compilers from fixed ones more accurately, I think you need to confine
the effects of the check to disabling inlining.
