* cp-namespace.c (cp_lookup_nested_type): New variable
concatenated_name. Turn the current return condition into a reverse
one. Call also lookup_static_symbol_aux on the constructed qualified
name.

other files into a called ...
(lookup_static_symbol_aux): ... new function here.

* valops.c (value_maybe_namespace_elt): Call also
lookup_static_symbol_aux if we failed otherwise.
