        * sdbout.c (sdb_debug_hooks): Same.
        * vmsdbgout.c (vmsdbg_debug_hooks): Same.
        * debug.c (do_nothing_debug_hooks): Same.

        testsuite:

        * g++.dg/debug/namespace1.C: New test.

        cp:

        * name-lookup.c: Include "debug.h"
        (do_namespace_alias): Invoke debug_hooks to emit debug info
