libmisc/loginprompt.c, libmisc/ttytype.c, libmisc/tz.c, src/login_nopam.c, src/chpasswd.c, src/chgpasswd.c, lib/port.c: 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.
