>Description:
I think that the error msg given when attempting the source file shown below is so confusing as to classify as a bug.
>How-To-Repeat:
Stick this code into a file and try to compile it:
class UI {
public:
UI::UI() {}
int member;
};
int main(void) {
UI *ui = new GUI;
}
>Fix:
add an include statement for GUI.h

State-Changed-When: Sat Jul 21 13:52:45 2001
State-Changed-Why:
I get,
3755.ii: In function `int main()':
3755.ii:8: parse error before `;' token
which seems adequate. Anyway, the new parser might change
it.
