Description:
------------
time_nanosleep(-1, 0); should trigger "Warning: time_nanosleep(): nanoseconds was 
not in the range 0 to 999 999 999 or seconds was negative" but on FreeBSD 8.2 it 
will just sleep 0 sec.
this also makes ext/standard/tests/misc/time_nanosleep_error3.phpt fail on FreeBSD

Test script:
---------------
<?php
time_nanosleep(-1, 0);

Expected result:
----------------
Warning: time_nanosleep(): nanoseconds was not in the range 0 to 999 999 999 or 
seconds was negative
