Thanks for the info. So apparently they added EOVERFLOW and ECANCELED but
not the others. Since I don't know which of the macros will be the last to
be implemented in future versions of OpenBSD, I'm applying this:


2008-09-15  Bruno Haible  <address@hidden>

        * m4/errno_h.m4 (gl_HEADER_ERRNO_H_BODY): Test for all the macros that
        are missing on OpenBSD 4.0 individually.
        Reported by Yoann Vandoorselaere <address@hidden>.
