If you've got AVR-GCC, then you've also got avr-libc, which contains a
few example programs.  Among them is the "simle demo":

http://www.nongnu.org/avr-libc/user-manual/group__demo__project.html

It has been made compile for nearly all AVRs that feature a timer 1.

Since it's small enough to post, here's the hex file when compiling
for an ATmega644:
