Gah, configure does pass - because AC_CHECK_HEADER(), if includes is not passed
in, first includes what's defined in AC_INCLUDES_DEFAULT.
https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Default-Includes.html#Default-Includes
Expand to include-directives if defined, otherwise to:
#include <stdio.h>
#ifdef HAVE_SYS_TYPES_H
# include <sys/types.h>
#endif
...
So maybe my memory is just faulty and the bsd_auth.h path never worked with
openbsd + meson. Anyway, it looks like Bilal's patch to just add this to meson
seems to suffice.
