Begginer that I am, it looks like you have declared the function readkey()
instead of using it.  The "int" before the function shows that it is a
declaration.  The compiler complains because it expects to see declarations
before you start doing other stuff in the function.

e.g. 
int main()
{ 
   /*declare & sometimes initialize stuff */
   int i = 2;
   int aFunction();    /* declares a function that's */
                             /* defined elsewhere */

   /*use stuff */
   printf("the number is %d\n", i);
   aFunction();
   return 0;
}

However, you don't have to declare the readkey() function because it is already
declared in the allegro.h file.  All you have to do is #include that file. 
Then you can just write stuff like the ex1.c file in your allegro/examples
directory.
