EGCS question

Hi!
Yesterday I spent 3 1/2 hours debugging code like this:

#include <SDL/SDL.h>
SDL_Surface *screen;

int main(int argc, char *argv[]) {
	SDL_Surface *screen;
	
	screen = SDL_SetVideoMode(640,480,8,0);
	drawRedSquare();
}

void drawRedSquare() {
	// do something with screen
	// SEGFAULT!
}

I kicked myself in the head when I found the problem:
duplicate declaration of screen at different scopes.
Is there any way to get EGCS to give me a warning about
this?
