with a leading '-', or when given any argument containing '\'. Avoid using 'echo' in these cases. * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely. * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise. * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise. * lib/autotest/general.m4 (AT_INIT): Likewise. * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the argument might be unportable. * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise. * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise. * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): (_AC_FC_LIBRARY_LDFLAGS): Likewise. * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise. * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE): (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST): (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise. * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise. * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise. * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): (AC_PROG_MAKE_SET): Likewise. * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER): (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise. * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT): (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED): (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME): (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise. * bin/autoconf.as: Redo verbose flag implementation, as the old scheme wouldn't work with AS_ECHO. * lib/autotest/general.m4 (AT_INIT): Likewise. * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED): Don't use ECHO_T, since ECHO_N is now reliable. * lib/autotest/general.m4 (AT_INIT): Likewise. * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script" rather than using a here-document to put the script into a file. (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can use AS_ECHO. * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise. * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any bug, but we might as well stop using ECHO_N and ECHO_C internally. * lib/autotest/general.m4 (AT_SETUP): Likewise. * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise. * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one operand, as AS_ECHO requires. Avoid double file name expansion. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE. Don't set as_nl, since _AS_ECHO_PREPARE does that now. (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code. (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros. * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Double-quote strings that would otherwise contain M4 comments. * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test. |

-*- 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 should install GNU M4 (version 1.4.7 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 1.4.7 here: ftp://ftp.gnu.org/gnu/m4/m4-1.4.7.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, 2006 Free Software Foundation, Inc.
