We still have a problem with the spurious declarations of:

(stdio.h)
/* These variables normally should not be used directly.  The `strerror'
   function provides all the needed functionality.  */
#ifdef  __USE_BSD
extern int sys_nerr;
extern __const char *__const sys_errlist[];
#endif
#ifdef  __USE_GNU
extern int _sys_nerr;
extern __const char *__const _sys_errlist[];
#endif

This trips up libiberty.

libiberty is peculilar in that it's not using AC_REPLACE to insert in
its objects.  It always compiles everything and decides what to do
within those source files based on `configure'-type defines.  It
should certainly be fixed, but we should also remove the declarations.

Drepper's response[0] suggests that he might not mind deprecating it
(if it hasn't been already) all over.
