Since there's no immediate fix in the foreseeable future, it might be
nice to mark the failing cases as `xfail's, so that others don't think
it's a regression.  That's the policy for C++, but not for C, so maybe
it doesn't apply here.  But then, it's not like it's a high-priority
bug...

Just my R$0,02 (it's Brazilian currency :-)
