You could code it in a plain Assambler file like this:

handler.S:
-----cut-----

.section .text

.global _interrupt0_
        .type   address@hidden

_interrupt0_:
/* save all needed registers here */
        nop
/* restore registers */
        reti
--------------

Then you compile and link this file just the same way you would do, if it
were a .c file.
