From f166d8653042df4b840c4d56fba752e266c8bffb Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 9 Mar 1997 06:16:49 +0000 Subject: Update. 1997-03-09 06:59 Ulrich Drepper * Makeconfig: Add ASFLAGS-% flags for SPARC assembler which need -fPIC. * Makerules (compile.S): Use ASFLAGS-%. (COMPILE.S): Likewise. * config.make.in (ASFLAGS-.so): Define from ASFLAGS_SO. * configure.in: Substitute ASFLAGS_SO. * sysdeps/sparc/configure.in: New file. * posix/unitstd.h: Add prototype for __euidaccess. * sysdeps/posix/euidaccess.c: Define as __euidaccess and make euidaccess weak alias. * sysdeps/stubs/euidaccess.c: Likewise. * inet/rcmd.c: Use __ protected versions of non-standard functions. * locale/setlocale.c (setlocale): Don't set usage_count to MAX_USAGE_COUNT if it already has this value. * locale/programs/localedef.c: Don't use LOCALE_PATH to find binary locale files. Use LOCALEDIR only. * locale/programs/locfile.c: When named file not found and not absolute use path in I18NPATH. * stdlib/Makefile (headers): Add inttypes.h. * sysdpes/generic/socketbits.h: Add PF_FILE as synonym for PF_LOCAL and AF_FILE as synonym for AF_LOCAL. * sysdpes/unix/sysv/linux/socketbits.h: Likewise. * time/Makefile: Rewrite rules for test to handle parallel builds. 1997-03-09 05:26 Ulrich Drepper * manual/startup.texi (EXIT_FAILURE): Fix typo. Patch by robbe@orcus.priv.at. 1997-03-09 05:10 Edward Seidl * sysdeps/i386/elf/start.S (nofini): *Really* align stack to 8-byte boundary. 1997-03-09 01:48 Ulrich Drepper * elf/link.h: Define __need_NULL to get definition. Include . Patch by Andreas Jaeger . 1997-03-08 21:48 Thorsten Kukuk Rewrite NIS code to allow empty keys. * nis/nss_nis/nis-ethers.c: Rewritten. * nis/nss_nis/nis-proto.c: Rewritten. * nis/nss_nis/nis-publickey.c: Rewritten. * nis/nss_nis/nis-rpc.c: Rewritten. * nis/nss_nis/nis-service.c: Rewritten. 1997-03-08 16:02 Andreas Jaeger * time/scheck.c (scheck): Add extra const to second argument. * time/private.h: Correct prototypes to match definition. 1997-03-08 18:55 Ulrich Drepper * sysdeps/alpha/__math.h: Remove cabs inline definition.
