[Bug c++/17421] New: g++ accepts invalid qualified declarator-id

["ppluzhnikov at charter dot net" <gcc-bugzilla at gcc dot gnu dot org>]

This is similar to, but not exactly like, bug 16782

$ cat junk.cc
void ::foo() { }

$ /usr/local/gcc-3.4.2/bin/g++ -c junk.cc -Wall
$ edgcpfe junk.cc
"junk.cc", line 1: error: the global scope has no "foo"
  void ::foo() { }
         ^
1 error detected in the compilation of "junk.cc".


The Standard (ISO+IEC+14882-1998) says in 8.3 paragraph 1:

 When the declarator-id is qualified,
 the declaration shall refer to a previously declared member of the
 class or namespace to which the qualifier refers, and the member
 shall not have been introduced by a usingdeclaration in the scope
 of the class or namespace nominated by the nested-name-specifier of
 the declarator-id.
