As a follow-up, I got the same error with dl-close.c from glibc and
assumed it was the same type of code but when I looked at it and cut it
down I got this code and error. This seems more like a real GCC error
(in that it should not be warning). Note that I only get the error when
bad is declared as 'noreturn'.
