	* locale/programs/localedef.c (main): Set bit in avail for those
	categories which are successfully read.
	* locale/programs/locfile.c (check_all_categories): Don't check
	categories if they are not available.
	(write_all_categories): Don't write categories if they are not
	available.

	* login/setutent_r.c (setutent_unknown): Change return type to
	int and return result of called function.

	* manual/arith.texi: Mark floating-point test macro from ISO C 9X
	as macros (not functions).

	* manual/math.texi: Document exceptions, functions to handle
	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.
	* manual/time.texi: Explain difficulties with strftime if the
	functions returns 0 and no error occurred.

	inunordered): Rewrite to make sure the arguments are evaluated
	exactly once.

	* nis/rpcsvc/nis.h: Likewise.
	* nis/rpcsvc/nislib.h: File moved back to here.

	* posix/sys/types.h: Don't define socklen_t.  Pretty print.

	getsockopt, setsockopt, accept): Change size argument to type
	socklen_t.
	Pretty print.
	* manual/socket.texi: Describe socklen_t and change prototypes of

	* sysdeps/unix/sysv/linux/bits/socket.h: Likewise.

	* stdlib/strtod.c: Fix typo.

	* 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.

	* wcsmbs/Makefile (tests): Add tst-wcstof.
	* wcsmbs/tst-wcstof.c: New file.

1997-08-01  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/m68k/__longjmp.c: Replace call to abort by infinite
	loop, to avoid dragging stdio into the dynamic linker.

	* posix/wordexp.c (parse_tilde): Fix calls to __getpwnam_r and
	__getpwuid_r.
	Include <stdio.h> to get prototypes of *printf.
	(exec_comm): Remove unneeded variable *sh.

	* libc.map: Add wordexp, wordfree.

	* posix/Makefile (routines): Add wordexp.
