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. Fri Oct 6 00:28:53 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * 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. Sun Sep 17 08:22:12 1995 Paul Eggert <eggert@twinsun.com> 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.
