--- Comment #3 from Florian Weimer <fweimer at redhat dot com> ---
It's a warning in the implementation, and that doesn't matter to us.

What would be problematic if GCC decided to eliminate stores to the fds arr=
ay,
assuming that it will be overwritten completely. But I don't think the
specification for write_only allows that. (write_only is perhaps misnamed.)
