[PATCH] test-generation.c: Fix a compiler warning

gcc complains as follows:

        CC test-generation.o
    test-generation.c: In function `main':
    test-generation.c:105: warning: control reaches end of \
        non-void function

In order to suppress the warning, we simply add a suitable
return statement to main().

Hi Junio,

Could you please squash this into commit 1784d096 ("test-generation:
compute generation numbers and clock skews", 04-09-2012).

Thanks!

ATB,
Ramsay Jones
