[ooc-compiler] Handling C "in" parameters

[August <fus...@co...>]

Hello all,

In my program I want to use some functionality from the SDL (Simple
Directmedia Layer) C library. The API contains the function:

int SDL_PollEvent(SDL_Event *event)

where `SDL_Event' is a union type. In the interface file I have the
definitions:

EventPtr* = POINTER TO Event;
Event* = RECORD [UNION] ... END;

PROCEDURE ["SDL_PollEvent"] PollEvent*(event: EventPtr): C.int;

If the client code contains:

event: EventPtr
...
NEW(event)

I get an error about `_td_Sdl__EventPtr' being undeclared. How do I
use/port this function?
