* lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
mode, we change to the source directory, also set $ac_pwd so we
do not go back to the build tree for the next config subdir.
* tests/torture.at (Deep Package): Extend test to contain two
config subdirs on the top level.
* tests/autotest.at (srcdir propagation): Copy install-sh to
source tree.
(my only test): Drop setting of `top_srcdir'.
* tests/base.at (Input/Output): Likewise.
* tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
config.guess, and config.sub to test source tree.
Drop AC_CONFIG_AUX_DIR setting.
(AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
* tests/torture.at (Substitute a 2000-byte string): Drop
AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
(Substitute a newline, datarootdir workaround): Likewise.
(Define a newline): Adjust for linenumber changes in configure.ac.
* tests/foreign.at (Libtool): Adjust comment to reflect changes.
The general idea is this: all write failures from `configure'
writing `config.status' are indicated by $ac_write_error, which
is only checked at the end. This is safe because config.status
code is not executed before the file is complete. Other write
failures, be they inside config.status, or in sub shell/awk
scripts spawned from configure or config.status, typically need
earlier checking, as their results are used right afterwards.
* lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
before writing config.status, check afterwards.
(_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
(_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
Set `ac_write_error' for write failures to config.status. Barf

Adjust note about closing and reopening the here-document.
(_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
(_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
reopening the here-document.
* tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
Ensure `ac_write_error' does not escape into config.status.
Also, add a couple of code paths not yet exercised in the test
suite: a config file with input from stdin, and a config header
output to stdout.

* tests/torture.at (Configuring subdirectories, Deep Package):
In the --help* tests in read-only trees, make `.' temporarily
writable again for the `stderr' file, and ignore errors due to
the attempt to write configure.lineno.
Report by Patrick Welche.
* tests/torture.at (Deep Package): Do not add `.' to $PATH
unnecessarily. Do not try running `/bin/sh configure' with a
configure script to be found in $PATH, if the shell does not do
this resolution. Fixes test failure on FreeBSD.
* lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Avoid errors when `.'
is not writable, use 'cp -p' in this case, in the hope that it
will not actually be needed. Still try removing files, in case
of other write errors.
* lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
use $as_myself, not $0.
(_AC_INIT_HELP): For --help=recursive, if the subdir does not
exist, try again in the the source tree. This change assumes
that the subpackage configure script is capable of running
--help=recursive in the source tree.

`sh configure ...' and plain `configure ...' with PATH adjusted.

The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
and CONFIG_COMMANDS are not processed in four separate loops.
Instead, there is one main loop. This alows that the common code
is expanded only once, thus config.status (and configure) is smaller.
The registration mechnism in AC_CONFIG_FILES and cousins also changed;
the AC_LIST_FILES and cousins macros are no longer used.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...

(_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
(AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,

* tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
(#define header templates): The comment at the top of the generated
header now includes the name(s) of the source file(s).
Several unrelated small changes:
* lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
parameter to AC_DIAGNOSE.
* lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
(_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages

(AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent

(AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
