...the bad news is it's because this patch inadvertently makes
all non-fortify-source compiles be no-optimization (and we already
knew the bug didn't repro in an unoptimized build).
This also explains the weird behaviour in bisect: it was only
when some later commit touched enough of the header files to
force recompilation of whichever object file it is that's
being problematic that the bug disappeared.
