I hesitated to suggest it because it's not my animal/time we're
talking about but it seems to make more sense.  It appears to be IBM's
answer to the nothing-builds-with-this-thing phenomenon, since it
accepts a lot of GCCisms via Clang's adoption of them.  From a quick
glance at [1], it lacks the atomics builtins but we have our own
assembler magic for POWER.  So maybe it'd all just work™.
