Rewrite mktime from scratch for performance, and for correctness
	in the presence of leap seconds.

	* time/mktime.c	(ydhms_tm_diff, not_equal_tm, print_tm, check_result):
	New functions.
	(LEAP_SECONDS_POSSIBLE, CHAR_BIT, INT_MIN, INT_MAX,
	TIME_T_MIN, TIME_T_MAX, TM_YEAR_BASE, EPOCH_YEAR): New macros.
	<limits.h>, <stdlib.h>: New #includes.
	(main): Support tests with given broken-down value; support benchmarks.
	(__mon_lengths, debugging_enabled, printtm, dist_tm, doit,
	do_normalization, normalize, BAD_STRUCT_TM, SKIP_VALUE,
	<ctype.h>): Remove.

	* time/time.h, time/mktime.c (__mktime_internal): New offset arg.
	* time/mktime.c (mktime), time/timegm.c (timegm): Use it.

	* time/mktime.c (__mon_yday): New variable; replaces `__mon_lengths'.
	time/offtime.c (__offtime), time/tzset.c (compute_change): Use it.
	
	* time/offtime.c (__offtime): Remove useless assignment
	`tp->tm_isdst = -1'.

	* manual/maint.texi: Update credits.

	* sysdeps/unix/common/readv.S: Moved to sysdeps/unix/bsd.
	* sysdeps/unix/common/writev.S: Moved to sysdeps/unix/bsd.
	* sysdeps/unix/sysv/linux/readv.c: File removed.
	* sysdeps/unix/sysv/linux/writev.c: File removed.
	* sysdeps/unix/configure.in: Check for readv and writev syscalls.

	* sysdeps/unix/configure.in: If eval doesn't set $unix_srcname,
	set it to $unix_syscall instead of $unix_function.

* mktime.c (localtime_r): Add substitute if the system doesn't
	provide one.

Mon Sep 18 14:39:20 1995  Roland McGrath  <roland@churchy.gnu.ai.mit.edu>

	* time/gmtime.c (gmtime_r): Define as weak alias.
	* time/localtime.c (localtime_r): Define as weak alias.
	* time/time.h [__USE_REENTRANT] (gmtime_r, localtime_r): Declare them.

	* errno.h: Only define _ERRNO_H #ifndef __need_Emath.
	#undef __need_Emath after including errnos.h.
	[_ERRNO_H]: Protect decls with this.

	Fix mktime so that it does not write over localtime's returned value.
	* localtime.c (__localtime_r): New function, with extra arg
	specifying where to store result.
	(localtime): Use it.
	(_tmbuf): New var.
	* gmtime.c (__gmtime_r, gmtime, _tmbuf): Likewise.
	* mktime.c (__mktime_internal):	Conversion function is now
	__localtime_r style, not localtime style.
	(mktime): Pass __localtime_r, not localtime.
	* timegm.c (timegm): Pass __gmtime_r, not gmtime.
	* offtime.c (__offtime): New arg specifying where to store result.
	* time.h (__mktime_internal, __offtime): Adjust decls accordingly.
	(__gmtime_r, __localtime_r): New decls.

	* time/localtime.c: <stddef.h>, <ctype.h>, <stdio.h>,
	<stdlib.h>, <string.h>: Remove includes.
	<errno.h>: Add include.

	* time/mktime.c, time/time.h, time/timegm.c (__mktime_internal):
	Renamed from _mktime_internal to avoid namespace pollution.

	* time/gmtime.c: Clear tm_isdst.

	* misc/efgcvt_r.c (ecvt_r, fcvt_r): Last arg is size_t, not int.
	* stdlib/stdlib.h (ecvt_r, fcvt_r): Fix type of last arg: make it
	size_t.

	* sysdeps/mach/hurd/fpathconf.c: Call __io_pathconf instead of
	__file_pathconf.
	* sysdeps/mach/hurd/pathconf.c: Likewise.
