I remember this biting me within the last ~4 years' time.

I don't know if it's still an issue or not, though, as we might have
places in our codebase where 'test -x' may have crept back in since

If there is an easy way to test for it, I'd rather there was something
like an AC_SANITY macro that would test for these ancient cases and
squawk if the running system botched them.
