--- Comment #5 from Paul Eggert <eggert at gnu dot org> ---
Thanks for the clarification, Joseph. I'll fix Gnulib accordingly. Marking the
bug as RESOLVED INVALID.
FWIW the comment 2 code works even with bleeding-edge clang because
__has_c_attribute (nodiscard) is still 0 in there.
PS. It is a bit annoying that one can't do this:
int f (int) [[nodiscard]];
as that would match the existing Gnulib style of putting attributes at the end
of the function declarations. I don't know whether such a thing could be added
as a GCC extension, but I suppose it's not worth the trouble since it wouldn't
be portable as per draft C2x.
