* config/install-sh: Don't use 'path' to talk about file names, as per GNU coding standards. Close a race condition reported by Ralf Wildenhues and Stepan Kasal. There is still a race condition on hosts that predate POSIX 1003.1-1992, but we can't help this. Don't mishandle weird characters like space on pre-POSIX hosts. Invoke mkdir at most once per dir arg on pre-POSIX hosts. * doc/autoconf.texi (Programming in M4sh): Cross-reference to AC_PROG_MKDIR_P from AS_MKDIR_P. (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P from mkdir. Mention that Autoconf 2.60 install-sh is safe but earlier editions are not (including Automake 1.8.3). Do not suggest mkinstalldirs for thread-safety. * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the presence of special characters and race conditions. * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables in Autoconf's name space. * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken from Automake with minor changes. * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
-*- 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 1.4.3 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.). You can get GNU M4 1.4.3 here: ftp://ftp.gnu.org/gnu/m4/m4-1.4.3.tar.gz 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 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'. Archives of bug-autoconf@gnu.org can be found in <http://lists.gnu.org/archive/html/bug-autoconf/>, and similarly for the other mailing lists. ----- Copyright (C) 1992, 1993, 1994, 1998, 2000, 2001, 2002, 2003, 2004, 2005 Free Software Foundation, Inc.
