From 5290baf06cbad096b1a085b2e20031b854e0226c Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 19 Jan 1997 04:54:28 +0000 Subject: update from main archive 970118 Sun Jan 19 04:38:20 1997 Ulrich Drepper * config.make.in (have-ksh, KSH): New variables. Will be filled in by configure. * configure.in: Add test for ksh like shell (prefer bash). * time/Makefile (tests): Depend on install-test-data. (distribute): Add simplebackw. (generated-dirs): New variable. [$(have-ksh)==yes] (install-others): Add iso3166.tab and zone.tab. (install-bin): Add tzselect. (install-test-data): Install the zoneinfo files which are needed for the test case in the build directory. (test-tz-ENV): New variable. Call test-tz program using data in build directory. * time/simpleback: New file. * time/test-tz.c: Pretty print. * time/tzfile.c: Use value of environment variable TZDIR as directory to look for zone info files. don't let search for DST data destroy already found values. * time/tzselect.ksh: Use @KSH@ and @TZDIR@ to be substituted when installing. * time/tzset.c (__tzset_internal): Avoid freeing string twice. Set DST zone name to normal zone name if no information is provided. * time/mktime.c (mktime): Call __tzset_internal to use current value of TZ. * Makerules (common-clean): Remove $(generated-dirs) inclusing content. * glibcbug.in: Fix several bugs. Reported by several people. * elf/Makefile: Correct dependecies for $(objpfx)ldd. * inet/netinet/ip.h: Define IPTOS_LOWCOST and IPTOS_MINCOST. * locale/C-time.c: Update copyright. * locale/localeinfo.h: Likewise. * sysdeps/unix/bsd/bsd4.4/direntry.h: Likewise. * locale/programs/ld-time.c (time_finish): Correct message string. * locale/programs/linereader.c (lr_token): Use correctly `number' not `digit' in message string. * stdlib/strtol.c [UNSIGNED]: Don't punt immediately when `-' is seen. Instead return ULONG_MAX and set ERANGE. * stdlib/tst-strtol.c: Correct test to reflect above change. Sun Jan 19 03:22:30 1997 Ulrich Drepper * sysdeps/unix/sysv/linux/sys/mtio.h: Don't use .

When used in glibc, make sure C locale format strings will always be recognized.
