^^^^^^^^
This should be "int main(void)" or "int main()"

The variables width and height should be defined and set before now.

This will centre the bitmap. If the bitmap is the same size as the screen
you can use "blit(bitmap_name, screen, 0, 0, 0, 0, SCREEN_W, SCREEN_H);"

Also, don't you need to mark broken lines with a "\" in DJGPP?
