expression of unbounded size when processing the --list
option. This runs afoul of a limit of 399 bytes per regular
expression on AIX. Problem reported by Ralf Wildenhues.
now contain newlines, and substituted files must be referenced on
a line alone; the sed scripts to substitute them are now very
different.
(_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
commands can be put in a sed script portably.
* doc/autoconf.texi (Setting Output Variables): Document above
changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
use of multiline substitution.
* tests/torture.at: No longer expect substitution of newline to fail.
* doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
* lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
* lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
avoid problems with C++ and throw.
* tests/compile.at: .cpp, not .cc.
Remove core.conftest.* too; it's generated by Tru64 5.1.
* lib/autoconf/functions.m4
(AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
Don't bother to remove core files; AC_RUN_IFELSE should do that for you.
a directory whose name contains a special character like space,
newline, or "\".
* doc/autoconf.texi (Installation Directory Variables): Allow
"," in file names. Do not use \@; it's not a portable regexp.

unportable file names.
* lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
(AC_INIT): Use it.
(_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
ac_pwd, and quote srcdir.
* lib/autotest/general.m4 (AT_INIT): Quote file name args.
/dev/null, as "configure" shouldn't read stdin, and this insulates
us from problems (e.g., when testing for "cl"). Also, do this
redirection before invoking "hostname" or "uname", and keep the
original input stream available via...
(AS_ORIGINAL_STDIN_FD): ... this new macro.
(_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
bother with "</dev/null" since it's now done at the top of
'configure'.

Suggested by Alexandre Duret-Lutz. Also, do this redirection
before invoking "hostname" or "uname".
(_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
_AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
* lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with

Also, replace grep with shell pattern-matching, to save a process.
