[Bug-gnulib] jm_FUNC_GETGROUPS calling-convention change (merge from coreutils)

[Paul Eggert]

I installed this merge from coreutils.  It changes the calling
convention for jm_FUNC_GETGROUPS.  I'll soon install a patch to
jm-macros that is required by (and depends on) this change.

2003-08-16  Jim Meyering  <address@hidden>

        * getgroups.m4 (jm_FUNC_GETGROUPS): Rewrite to use AC_FUNC_GETGROUPS
        and (if needed) to call AC_LIBOBJ and to set GETGROUPS_LIB.
