1996-09-15  Paul Eggert  <eggert@twinsun.com>

	* manual/time.texi: Change `range X to Y' to `range X through

	(strftime): Numbers that do not have a range indicated are not padded.
	Describe E and O modifiers.
	%g, %G, %u: New formats.
	%C, %y, %Y: Describe behavior on negative years.
	%e: Fix typo (was labeled %d).
	%l, %V: Fix typo in range.
	%M, %S, %U, %w, %W: Give ranges.
	%p: Clarify how noon and midnight are handled for AM and PM.
	%s: Clarify leap second handling.
	%r: Now locale-defined.
	%C, %D, %e, %h, %n, %r, %t, %T: Say that they are POSIX.2 extensions.
	%z: Say that it is a GNU extension.
	%Z: Wording fix.

	* time/strftime.c: (strftime):
		%V: Fix mishandling of week numbers near year boundaries.
		%g, %G: New formats (suggested by Arthur David Olson).
		%U, %W: Use inline expression instead of `week' function.
		%C, %y: Handle negative years portably.
		%C, %Y: Use width 1, since values can be arbitrarily wide.
		%r: Use T_FMT_AMPM format if _NL_CURRENT is defined.
		%u: New Posix.2 format.
		%w: Width is 1, not 2.
	(iso_week_days): New function, for %V, %G, %g.
	(week): Remove; it didn't handle %V correctly.
	(__isleap): New macro.
	(mbsinit): Use arg, to pacify GCC -Wall.

1996-09-13  Paul Eggert  <eggert@twinsun.com>

	* time/strftime.c (strftime):
	If using the GNU C library, do not bother to check for
	multibyte encodings, since they're safe in formats.  Otherwise:
	  - Check for multibyte encodings when encountering any character that
	  is not in the basic execution character set of the C Standard.
	  - Use mbrlen (if available) instead of mblen, to avoid modifying
	  mblen's internal state.
	  - Do not assume that '%' cannot appear as the first character of a
	  multibyte character sequence, since this is possible when not in the
	  initial shift state.
	(HAVE_MBRLEN, MULTIBYTE_IS_FORMAT_SAFE): Define if _LIBC is defined.
	(DO_MULTIBYTE): New macro.
	(<ctype.h>): Do not include.
	(<wchar.h>): Include if HAVE_MBRLEN.
	(mbstate_t, mbrlen, mbsinit): Define if ! HAVE_MBRLEN.
	(mbstate_zero): New constant.

1996-09-12  Paul Eggert  <eggert@twinsun.com>

	* time/strftime.c (strftime):
	Use an empty zone if it can't be determined; POSIX.2 requires this.
	Use plain `int' for pad and modifier (which now contain char value).
	Use plain `int' for number_value, to print negative values correctly.
	Use plain `int' for digits; there was no need to make it unsigned.
	Initialize subfmt consistently.
	Remove incorrect code for %EC and %Ey; they aren't implemented yet.
	For %O, if there is no alternate digit, output Ascii instead of "".
	Output the `%' of an unknown format; this is most likely the right
	thing to do if a multibyte string has been misparsed.

Thu Sep 12 23:23:13 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* stdio-common/scanf7.c (main): Remove extra conversion from
	printf format string.

Thu Sep 12 23:01:16 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	Removed.
	* sysdeps/m68k/fpu/s_ldexp.c, sysdeps/m68k/fpu/s_ldexpf.c,
	sysdeps/m68k/fpu/s_ldexpl.c: Removed, use generic implementation
	instead.
	* sysdeps/m68k/fpu/s_scalbn.c, sysdeps/m68k/fpu/s_scalbnf.c,
	sysdeps/m68k/fpu/s_scalbnl.c: Replaced with old contents of
	s_ldexp.c, s_ldexpf.c and s_ldexpl.c, resp., suitably adpted.

	* sysdeps/m68k/fpu/__math.h (__frexp, __frexpf, __frexpl):
	Return value must be in [0.5, 1), not [1, 2).  Reported by Chris
	Lawrence.
	(__ilogb, __ilogbf, __ilogbl): Check for argument being zero.
	(__scalbn, __scalbnf, __scalbnl): Use second argument directly.

	(__funlockfile): Don't use weak_extern for this one;
	__libc_cleanup_region_end might be defined and the use of
	__funlockfile can't be protected the way the use of __flockfile
	can be.

	* sched.h: New file.  Helper to access posix/sched.h.
