Thu Aug 29 00:28:08 1996 Ulrich Drepper <drepper@cygnus.com> * stdio-common/printf_fp.c (__printf_fp): Use default value `.` if `decimal' char is 0. * C-numeric.c (not_available): New constant. (_nl_C_LC_NUMERIC): Use `not_available' for grouping value. * nss/nsswitch.conf: Example configuration file. * nss/db-Makefile: Example Makefile for generation of databases for nss_db. * nss/Makefile (distribute): Add nsswitch.conf and db-Makefile. 1996-08-28 Paul Eggert <eggert@twinsun.com> * C-messages.c (_nl_C_LC_MESSAGES): Set yesexpr to "^[yY]" and noexpr to "^[nN]"; this conforms to POSIX.2. * C-time.c (_nl_C_LC_TIME): Change %d to %e in d_t_format, to conform to POSIX.2. 1996-08-28 Paul Eggert <eggert@twinsun.com> * C-monetary.c (not_available): New constant. (_nl_C_LC_MONETARY): Set mon_decimal_point to "", and set mon_grouping, int_frac_digits, frac_digits, p_cs_precedes, p_sep_by_space, n_cs_precedes, n_sep_by_space, p_sign_posn, and n_sign_posn to CHAR_MAX, as required by the POSIX Standard. Wed Aug 28 23:12:28 1996 Ulrich Drepper <drepper@cygnus.com> * nss/nss_db/db-XXX.c: Correct function names. They must be `_nss_db_*' instead of `_nss_files_*'. (lookup): `parse_line' returns 1 if succesful. * nss/nss_files/files-service.c (servbyname): Key for database must also contain protocol names. (servbypt): Likewise. Test must also check for protocol. Add `proto' argument. Tue Aug 27 09:56:13 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * MakeTAGS ($P/subdirs.pot): Prefix all file names, not only the first one. Fri Aug 16 16:11:25 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * nss/nss_dns/dns-host.c (_nss_dns_gethostbyname2_r): Treat EPFNOSUPPORT and EAFNOSUPPORT as implying NSS_STATUS_UNAVAIL just like ECONNREFUSED already does. (_nss_dns_gethostbyaddr_r): Likewise. * nss/nss_dns/dns-network.c (_nss_dns_getnetbyname_r): Likewise. (_nss_dns_getnetbyaddr_r): Likewise. * sysdeps/mach/hurd/socket.c (socket): For message transmission and RPC errors that indicate that the socket server is not really present and able to do its job, turn the error into EPFNOSUPPORT. * sysdeps/generic/sbrk.c (__sbrk): Get kernel brk address always only if in static libc or if statically linked program uses libc.so.
