1003.1-2001's requirements for CDPATH. Give a simpler workaround for the CDPATH problem. Document PWD. (Limitations of Builtins): Document the problem that "cd $foo" and "ls $foo" may refer to different directories in shells conforming to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset" example, since the old example is now out of date. * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd FOO" and "ls FOO" talk about different directories; this catches problems when POSIX 1003.1-2001 "cd" fails due to symlink spaghetti. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead of rolling our own unset. (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since in practice we needn't worry about CDPATH if unset doesn't work. * Makefile.in, aclocal.m4, bin/Makefile.in, config/Makefile.in, doc/Makefile.in, lib/Makefile.in, lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in, lib/autoscan/Makefile.in, lib/autotest/Makefile.in, lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in, tests/Makefile.in: Regenerate with Automake 1.6.3. * config/config.guess, config/config.sub, config/mkinstalldirs: Update. * configure: Regenerate with self. |

-*- text -*- Autoconf Autoconf is an extensible package of M4 macros that produce shell scripts to automatically configure software source code packages. These scripts can adapt the packages to many kinds of UNIX-like systems without manual user intervention. Autoconf creates a configuration script for a package from a template file that lists the operating system features that the package can use, in the form of M4 macro calls. Producing configuration scripts using Autoconf requires GNU M4 and Perl. You must install GNU M4 (version 1.4 or later) and Perl (5.005_03 or later) before configuring Autoconf, so that Autoconf's configure script can find them. The configuration scripts produced by Autoconf are self-contained, so their users do not need to have Autoconf (or GNU M4, Perl etc.). The file INSTALL should be distributed with packages that use Autoconf-generated configure scripts and Makefiles that conform to the GNU coding standards. The package's README can just give an overview of the package, where to report bugs, and a pointer to INSTALL for instructions on compilation and installation. This removes the need to maintain many similar sets of installation instructions. Be sure to read BUGS (especially if this version is not an official release) and INSTALL. Mail suggestions to autoconf@gnu.org, report bugs on http://bugs.gnu.org/cgi-bin/gnatsweb.pl?database=autoconf or to bug-autoconf@gnu.org, and submit patches to autoconf-patches@gnu.org. Always include the Autoconf version number, which you can get by running `autoconf --version'. ----- Copyright (C) 1992, 1993, 1994, 1998, 2000, 2001, 2002 Free Software Foundation, Inc.
