In my project, I'd implement ISR in library modules and include the 
header in the file contains main() function:

main.c:

   #include <mylib.h>

   void main() { ... }

mylib.h:

   void isr_xxx() interrupt yyy;

mylib.c:

   #include <mylib.h>
   void isr_xxx() interrupt yyy { ... }


and link main.c with mylib.o, the ISV is correctly generated in the 
result binary.
