	The size argument of fgets is an int, not a size_t.
	* libmisc/loginprompt.c: Ignore the return value from signal()
	when the signal handlers are restored.
	* src/chpasswd.c: Cast the return value of time() to a long
	integer.
	* src/chpasswd.c: Use the SCALE macro instead of (24L * 3600L)
	for the values to be set in /etc/shadow.
