You should declare or define all functions that you're calling, before
you call them.

If you move main() to the beginning of the program (which is what I
believe you're trying to do), the compiler hasn't yet seen
port_init(), which you're calling from main().

You could do this:

void port_init(void); /* declare it */

void main(void)
   /* stuff */

void port_init(void) /* define it */
/* stuff */
