The observation that (__AIX && !__GNU__) -> vendor=ibm sounds like a
safety net for unknown compilers.
I think that since the current problem is specific to the Linux
sched_setaffinity() probe, that ignoring that case is safe.
BTW: output of xlc when given no arguments is an entire manpage, not
just the version info!
It occurs to me now that xlc MIGHT have an option to make only the
specific (E) become fatal.
I will look and report back.
