string for more reliable failure. Wrap the entire test that
causes the broken Solaris printf to dump core, in a subshell,
so the segmentation fault message is reliably suppressed.
Fix shell expansion errors by using /usr/ucb/echo always;
avoid an error on systems without it by another subshell.
Avoid m4 expansion of `$1'. Set the zeroth argument of the
subshell-$as_echo to `as_echo', for better error message.

(_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
generate just one large awk script for substitutions,
eliminating much of the earlier complexity, while adding some
new complexity. Only expand the substitution templates at
configure time, for smaller configure script size. If
_AC_SUBST_FILES are used, test 'awk' for working getline support
at config.status time. If absent, interpolate through the
shell. The awk script was written with much help
from Paolo Bonzini and Paul Eggert.

output, to test that no recursion happens; test several other
combinations from Paolo Bonzini.

(Backquote in a test title,

Double-quote in a test title): Don't expect failure anymore.

backslash so that Bourne shells might actually see it as an escape
sequence.
(Brackets in a test title,

Comma in a test title,
Quoted Macro in a test title,
Macro in a test title,
Macro with single-quote in a test title): New tests.

* tests/m4sh.at (AS_LITERAL_IF): New test.
* build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
which incorrectly sets the mode of an existing destination
directory. In some cases the unpatched install-sh could do the
equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
system. We hope this is rare in practice, but it's clearly worth
fixing. Problem reported by Alex Unleashed in

(\lquoteexpand, \quoteexpand): new defs.
(\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
(\code): must use new \...Char values, since now ` is active.

2006-08-12 Karl Berry <karl@gnu.org>

(AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
(_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
Use a better substitute, by inspecting the output of "ls"

set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
nobody uses it.
(_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
with werror_flag and conftest.err and so forth. This is more
compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
and anyway the user shouldn't normally want to see this gorp logged.
Problem reported by Ralf Wildenhues.
