--- Comment #6 from Warner Losh <imp@FreeBSD.org> ---
The other workaround for this would be to add -D__BSD_VISIBLE=3D1 to the
compliation.

The hdf sources already do something similar for _GNU_SOURCE to bring in ex=
tra
functionality that's only in Linux, but we have no similar _BSD_SOURCE or
_FREEBSD_SOURCE (NetBSD and OpenBSD both have _NETBSD_SORUCE or _OPENBSD_SO=
URCE
respectively). My inclination is to define _FREEBSD_SOURCE and have hdf use=
 it
(and maybe __BSD_VISIBLE=3D1 as a transitionary workaround), but I'm open f=
or the
least painful way to be both compliant with POSIX_C_SOURCE and the desire f=
or
enabling extensions.
