Marking of functions with attributes like __wur

[Roland McGrath]

I'm not sure the "security problem or always bug" predicate is really the
appropriate one.  Warnings exist to help programmers.  So "more likely to
be unintended than intended" might be a reasonable predicate.  OTOH, __wur
doesn't make it easy to suppress the warning explicitly with something like
a (void) cast, which IMHO would be more reasonable behavior.

Certainly strtoll and strtoimax should be completely consistent in all
aspects of their APIs aside from the actual integer type used.


Thanks,
Roland
