System: Linux kiste 2.4.2 #34 Sun Feb 25 20:03:34 CET 2001 i686 unknown
Architecture: i686

>Description:
Recently I came across the following code te.C. G++ 2.95.2 accepts
the code but gcc 3 does not. Is this code legal?
>How-To-Repeat:
Source code te.C
class exception
{
public:
bool flag;
void proc(void) throw(exception);
};
Compiling te.C
g++ -v -c te.C -W -Wall
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/specs
