Both of these fail on Haiku. I'm adding these two workarounds.

        errno tests: Avoid test failure on Haiku.
        * doc/posix-headers/errno.texi: Mention the Haiku problem.
        * tests/test-errno.c: On Haiku, don't check that the error numbers are
        positive.

        errno: Ensure ESOCKTNOSUPPORT gets defined.
        * m4/errno_h.m4 (gl_HEADER_ERRNO_H): Test also whether ESOCKTNOSUPPORT
        is defined.
        * lib/errno.in.h (ESOCKTNOSUPPORT, GNULIB_defined_ESOCKTNOSUPPORT): New
        macros.
        * lib/strerror-override.h (strerror_override): Declare also if
        GNULIB_defined_ESOCKTNOSUPPORT is defined.
        * lib/strerror-override.c (strerror_override): Handle ESOCKTNOSUPPORT.
        * lib/strerrorname_np.c (strerrorname_np): Move ESOCKTNOSUPPORT code to
        the POSIX section.
