Re: autoconf-2.69c released [beta]

[Bruno Haible]

Hi Paul,

I had been wondering why my patch with m4_version_prereq([2.70], ...) was
not effective, when you pointed me to the version numbering :)

This should do it.


2020-09-27  Bruno Haible  <bruno@clisp.org>

        Enable testing of prereleases of Autoconf 2.70.
        Suggested by Paul Eggert in
        <https://lists.gnu.org/archive/html/bug-gnulib/2020-09/msg00160.html>.
        * m4/alloca.m4 (_AC_LIBOBJ_ALLOCA): Test for Autoconf >= 2.69c, not
        >= 2.70.
        * m4/largefile.m4 (AC_SYS_LARGEFILE): Likewise.
        * m4/pid_t.m4 (AC_TYPE_PID_T): Likewise.
        * m4/sys_types_h.m4 (AC_HEADER_MAJOR): Likewise.
