	exceptions, mathematical constants, FP comparison functions
	and several new functions from ISO C 9X.
	Change parameter of drand48, lrand48, and mrand48 to void (not
	empty).
	* manual/pattern.texi: Remove paragraph which explained that wordexp
	is executed by running a shell.

	socklen_t.
	Pretty print.
	* manual/socket.texi: Describe socklen_t and change prototypes of

	* string/Makefile (headers): Add bits/string.h.
	(CFLAGS-*): Add -D__NO_STRING_INLINES.
	* string/string.h: Include <bits/string.h> if optimizing and
	__NO_STRING_INLINES is not defined.
	* sysdeps/stub/bits/string.h: New file.

	* sysdeps/powerpc/bits/fenv.h: Fix typos.

	* sysdeps/unix/sysv/linux/if_index.c: Let functions return ENOSYS
	if SIOGIFINDEX is not defined.

	* sysdeps/wordsize-32/inttypes.h: Pretty print.
	* sysdeps/wordsize-64/inttypes.h: Pretty print.

	* termios/cfsetspeed.c: Rewrite loop to do what it shall do.

	(exec_comm): Remove unneeded variable *sh.

	* libc.map: Add wordexp, wordfree.

	* posix/Makefile (routines): Add wordexp.
