Hi,

When compiling the example program from Documentation/rtc.txt there is a
tiny compiler warning about main() not returning int. That is no big
deal, but for the sake of correctness (and since main actually does
return a value on error) I have made a small patch to fix it (see below,
patch also attached as 'rtc.txt-patch').

The patch is pretty self explaining. It changes the return type of main
to int and adds a call to exit(0) at the end of main(), so now we have
killed the warning and return a meaningfull value on sucessfull completion.

The patch is against vanilla 2.4.3 and applies cleanly and the program
in rtc.txt compiles and runs without a problem after applying the patch.

I hope you like the patch and will apply it (comments and criticism is
welcome) :-)
