[uClibc-cvs] uClibc/libc/unistd sleep.c,1.5,1.6

[David McCullough]

Update of /var/cvs/uClibc/libc/unistd
In directory winder:/tmp/cvs-serv14019

Modified Files:
	sleep.c 
Log Message:

Sleep was returning the wrong value because:

* nanosleep returns the remaining time,  not the time slept

* nanosleep only fills out the remaining time if it returns -1 (ie., the
  sleep was interrupted)

Fix from Paul Dale <pauli at snapgear.com>
