[Bug c++/33287] namespace hides class definition

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #6 from reichelt at gcc dot gnu dot org  2007-12-26 19:40 -------
To sum things up:

* The code is invalid, i.e. it shouldn't compile.

* GCC up to 4.2.x rejected the code for the wrong reason:

    bug.cc:24: error: 'C1' does not name a type

  This message is way too late.
  GCC should have rejected the declaration of the namespace C1.

* Mainline GCC produces a correct diagnostic:

    bug.cc:12: error: 'namespace C1 { }' redeclared as different kind of symbol
    bug.cc:2: error: previous declaration of 'class C1'

  This is due to the fix mentioned in comment #2, namely for PR 30734,
  aka PR 2708. Since this bug wasn't a regression, the fix won't be
  backported to current branches.

Although the submitter probably thought of the problem as an rejects-valid
bug, this is really an accepts-invalid bug in the first place.
