Forward class in throw declaration.

["Andrew J. Malton" <ajmalton at uwaterloo dot ca>]

The following snippet uses a forward class name in a throw declaration:

class F {
     int v;
public:
     F (int v) { this-> v = v; }
     void raise () throw (F) { throw new F (0); }
};

It compiles and works perfectly well using "gcc version egcs-2.91.66 
19990314/Linux (egcs-1.1.2 release)" and "gcc version 2.95.2 19991024 
(release)" but when compiled with "gcc version 3.0" it fails to parse:

F.cpp:5: invalid use of undefined type `class F'
F.cpp:1: forward declaration of `class F'

Is this a bug, or newly correct ;-) behaviour, or am I missing something?
