Sure.  It's all GPL.  The 6-1.c test case (attached below) probably has the
best test because it does multiple values, some < 0, some >= 1000 million.

One other thing I forgot to write in my previous report is that
clock_nanosleep() appeared to behave as expected, just nanosleep() showed
the issue of returning 0 on failure.

Thanks.
