Use a double buffer in your program..

blit everything to a seperate bitmap(the size of your screen) and when
everything is drawn there, then blit the seperate bitmap to the screen.

like:

BITMAP *buffer=create_bitmap(320, 200);

do
    {
    x=x+1;
    blit(happyface, buffer, 0, 0, x, y, 20, 100);
    blit(bird, buffer, 0, 0, x, y, 10, 10); 
    
    blit(buffer, screen, 0, 0, 0, 0, 320, 200);
    clear(buffer);
    }while(whatever)

doing this eliminates the flicker...try it.
