 version-controlled and up to date.
 
-Implement Ulrich Drepper's suggestion to use getgrouplist rather than
-  getugroups.  This affects both `id' and `setuidgid', but makes a big
-  difference on systems with many users and/or groups, and makes id usable
-  once again on systems where access restrictions make getugroups fail.
-  But first we'll need a run-test (either in an autoconf macro or at
-  run time) to avoid the segfault bug in libc-2.3.2's getgrouplist.
-  In that case, we'd revert to using a new (to-be-written) getgrouplist
-  module that does most of what `id' already does.  Or just avoid the
-  buggy use of getgrouplist by never passing it a buffer of length zero.
-  See http://bugzilla.redhat.com/200327

 remove `%s' notation (now that they're all gone, add a Makefile.maint sc_
     rule to ensure no new ones are added):
   grep -E "\`%.{,4}s'" src/*.c
