	* time/strptime.c: Recognize %s, %u, %g, and %G format.
 	nothing is found.  This guarantees all subsequent calls behave
	* sysdeps/unix/sysv/linux/syscalls.list: Change function name for
	* io/getwd.c (getwd) [! PATH_MAX]: Don't assume that the user's
	buffer is any longer than the amount necessary to hold the
	filename; the Hurd getcwd uses the *entire* contents of the
	buffer, however long it is specified to be.
	* posix/getconf.c: De-ANSI-fy.  Recognize POSIX.2 constant names.
	since these do not depend on the platform.
