/* GNU has no arbitrary fixed limits on these things, so we don't
   define the macros.  Some things are unlimited.  Some are in fact
   limited but the limit is run-time dependent and fetched with
   `sysconf' or `pathconf'.

   POSIX.1 requires that we define NGROUPS_MAX (though none of the others
   is required).  GNU allows any number of supplementary groups,
   dynamically allocated.  So we pick a number which seems vaguely
   suitable, and `sysconf' will return a number at least as large.  */
