update from main archive 961201cvs/libc-961202
Mon Dec 2 03:59:38 1996 Ulrich Drepper <drepper@cygnus.com> * grp/initgroups.c: Update and reformat copyright. Use __getgrent_r instead of getgrent. * inet/rcmd.c: Update and reformat copyright. Use __gethostbyname_r instead of gethostbyname. * inet/rexec.c: Likewise. * intl/finddomain.c: Correct comment about CEN sponsor and revision. * locale/findlocale.c: Likewise. * intl/l10nflist.c: Correct handling of CEN sponsor and revision. * locale/Makefile (CPPFLAGS): Add definition of LOCALEDIR. * locale/setlocale.c (setlocale): Correctly split value of LOCALE_PATH. * locale/programs/localedef.c: Use LOCALEDIR not LOCALE_PATH to find output directory. * nss/getXXbyYY.c [NEED_H_ERRNO]: Before enlarging buffer test h_errno_tmp variable. Save error value from being changed during `free' call. * nss/getXXent.c: Likewise. * nss/nss_files/files-XXX.c: Set h_errno variable to NETDB_INTERNAL before returning ERANGE error. * posix/glob.c: Use getlogin_r and getpwnam_r function when available or in GNU libc. * pwd/getpw.c: Use getpwuid_r instead of getpwuid. * sunrpc/clnt_gen.c: Use gethostbyname_r and getprotobyname_r. * sunrpc/clnt_simp.c: Likewise. * sunrpc/getrpcport.c: Likewise. * sysdeps/unix/sysv/linux/gethostid.c: Likewise. * posix/getconf.c: Treat _SC_UNIT_MAX and _SC_ULONG_MAX separately since the value might be outsode the range of the `long int'. Print string `undefined' when a value is undefined. * stdlib/l64a.c: Return correct pointer. Patch by NIIBE Yutaka <gniibe@mri.co.jp>. * string/Makefile (routines): Add argz-addsep. * string/argz-addsep.c: New file. * string/argz.h: Add prototypes for argz_add_sep. * string/argz-ctsep.c: Prevent memory leak. * string/strcoll.c: Correct typo in comment. Sat Nov 30 02:53:59 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/sys/serial.h: Removed again. The file is not general enough to be part of the libc. * sysdeps/unix/sysv/linux/Dist: Remove sys/serial.h. * sysdeps/unix/sysv/linux/Makefile: Don't install sys/serial.h. Thu Nov 28 20:04:41 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * login/Makefile: Fix typo. * nss/Makefile (generated): Filter out db-alias.c. Thu Nov 28 14:44:01 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * time/Makefile (echo-zonenames): Don't depend on non-existing target `zonenames'. Thu Nov 28 12:34:05 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * link.h: New file. * nss/nsswitch.c: Use it. * printf.h: Fix file name. * stdlib/strfmon.c: Use it.
