I don't think you want two copies of this linked in.

Same here.  That should take care of the multiple defines.

This next one is not a link error, this is a Pre-processor error.

My guess is that stdio.h has a line like this (don't have the header files
here to verify)

#define EOF something

and Allegro.h has a line like this

#ifndef EOF
#define EOF somthing
#endif

If this is the case then

#include <stdio.h>
#include <allegro.h>

should work, just don't include allegro.h first.
