Should this really be valid code? I can't imagine any reasonable semantics for 
it...

------- Additional Comments From mmitchel at gcc dot gnu dot org  2004-03-01 00:08 -------
This code is not valid, despite being accepted by GCC 2.95.3.

While we should certainly issue a better error message, this is not a
showstopper; I have moved the target milestone to 3.4.1.
