Richard Stevens, published by Prentice Hall PTR. That publication is Copyright (c) 1998 Prentice Hall PTR. These items are: src/daemonize.c src/get_myeaddr.c src/get_myipaddr.c AC_CHECK_FUNC_PROTO in aclocal.m4 and m4/ac_check_func_proto.m4 AC_UNP_CHECK_TYPE in aclocal.m4 and m4/ac_unp_check_type.m4 The sample code associated with that book is available from: ftp://ftp.kohala.com/pub/rstevens/unpv12e.tar.gz ========================================================================= The macro AC_CHECK_STRUCT_FOR in aclocal.4 is copyrighted by Wes Hardaker , and was obtained from the GNU autoconf macro archive at http://research.cys.de/autoconf-archive/ Permission has been granted to use and distribute it under the following license, which is a modified version of the GNU General Public License version 2: Every Autoconf macro presented on this web site is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2, or (at your option) any later version. They are distributed in the hope that they will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. (You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place -- Suite 330, Boston, MA 02111-1307, USA.) As a special exception, the Free Software Foundation gives unlimited permission to copy, distribute and modify the configure scripts that are the output of Autoconf. You need not follow the terms of the GNU General Public License when using or distributing such scripts, even though portions of the text of Autoconf appear in them. The GNU General Public License (GPL) does govern all other use of the material that constitutes the Autoconf program. Certain portions of the Autoconf source text are designed to be copied (in certain cases, depending on the input) into the output of Autoconf. We call these the "data" portions. The rest of the Autoconf source text consists of comments plus executable code that decides which of the data portions to output in any given case. We call these comments and executable code the "non-data" portions. Autoconf never copies any of the non-data portions into its output. This special exception to the GPL applies to versions of Autoconf released by the Free Software Foundation. When you make and distribute a modified version of Autoconf, you may extend this special exception to the GPL to apply to your modified version as well, *unless* your modified version has the potential to copy into its output some of the text that was the non-data portion of the version that you started with. (In other words, unless your change moves or copies text from the non-data portions to the data portions.) If your modification has such potential, you must delete any notice of this special exception to the GPL from your modified version. ========================================================================= A number of items are based on code from LPRng-2.0.8: * the macros AC_SYS_NERR, AC_SYS_ERRLIST, AC_DECL_SYS_ERRLIST, AC_DECL_SYS_ERR_DECL. These are in aclocal.m4 and also in m4/sys_errlist.m4. The macros are based very closely on code from LPRng's configure.in file. * much of lib/strerror.c The macros are based very closely on code from LPRng's configure.in file. LPRng-2.0.8 is distributed under the GNU General Public License (see the COPYING.GPL file). ========================================================================= The file INSTALL is the generic installation INSTALL document provided with many GNU products.
