what sort of listbox are you getting? when pressing CTRL-SPACE for a completion listbox i am not seeing reinterpret_cast listed, so i cannot accept it.
i can get reinterpret_cast suggested via a suggestion listbox (question mark icons) but this is not inserting any such brackets for me.
It's the suggestion listbox. PROC is declared in windef.h so including windows.h should do it. I get those brackets only if I want to cast from a function pointer.
