It works fine for me using a 2.2.16 kernel and egcs-2.91.66 (see below)...
bash-2.04$ gcc -s -Wall -Wstrict-prototypes rtc2.c -o rtc2
rtc2.c:24: warning: return type of `main' is not `int'
bash-2.04$ ./rtc2
RTC Driver Test Example.
Counting 5 update (1/sec) interrupts from reading /dev/rtc: 1 2 3 4 5
Again, from using select(2) on /dev/rtc: 1 2 3 4 5
Current RTC date/time is 20-4-2001, 12:34:01.
Alarm time now set to 12:34:06.
Waiting 5 seconds for alarm... okay. Alarm rang.
Periodic IRQ rate was 1024Hz.
Counting 20 interrupts at:
2Hz: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
4Hz: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
8Hz: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
16Hz: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
32Hz: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
64Hz: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
*** Test complete ***
Typing "cat /proc/interrupts" will show 131 more events on IRQ 8.
bash-2.04$
