Message-ID: <E1uWe2G-004DSs-0e@gemulon.postgresql.org> (raw)
Make sure IOV_MAX is defined.
We stopped defining IOV_MAX on non-Windows systems in 75357ab94, on
the assumption that every non-Windows system defines it in <limits.h>
as required by X/Open. GNU Hurd, however, doesn't follow that
standard either. Put back the old logic to assume 16 if it's
not defined.
