`{ cmd; } 2>/dev/null', when cmd has no side effects and might be a
builtin. Note that it is unspecified whether cmd will run within a
subshell (e.g. Bourne shells) or within the current shell (most modern
shells).
inherited_linker_flags so it puts it on the link line when
linking shared libraries as well as when linking executables.
* tests/inherited_flags.at: test inherited_linker_flags.
* tests/Makefile.am: Add test.
* tests/testsuite.at: Add test.

within the same and following line.
* config/ltmain.m4sh (func_enable_tag, func_mode_install)
(func_mode_link): Sprinkle `shift's all over to conform to this.
Use `$SED -n' instead of `$SED RANGE {..}; d' as AIX sed cannot
handle the latter.
(func_help): start autoconf and automake in subshells to avoid
error messages from ash or Bourne shell if not available.
New variable $opt_debug is either `:' or `set -x' depending on --debug.
Execute at most function entries to cater for ksh which resets `-x'.
* tests/defs.m4sh: Ditto for VERBOSE=debug.
(func_quote_for_eval, func_quote_for_expand) ..use it to work around
SunOS ksh `case' backslash-escaping bug: protect character class by
variable expansion. Reported by Alexander Kurz <alexander.kurz@qsc.de>.
On darwin, uniq can not take the flags -cd together, thanks to Ralf
for the fix, also ar does not accept N, so we use the fact that
ar x libfoo.a foo.o will always extract the first foo.o in the
archive and we then delete foo.o from the archive, which will also
delete only the first foo.o, then rinse and repeat. Also add markers
for the testuite.
* m4/libtool.m4 (_LT_CONFIG): Add a marker so that we can use a sed
expression to find the shell functions in libtool.
* tests/functests.at: Test this feature.
* tests/testsuite.at: Add the test.
* tests/Makefile.am: Add the test.
does not need the `g' flag.
(func_quote_for_eval): Return both the possibly double-quoted
backslashified as well as only the backslashified argument.
* config/ltmain.m4sh (func_mode_link): Use both return values,
to save another sed_quote_subst application per cmdline arg.
description. (func_lalib_unsafe_p): New function with same
functionality but written without forks; this function is safe
to use for cases where the argument either does not exist or
is required to be a lalib for correct operation.
* NEWS: Mention the fact that stdin is not to be used.
* (func_mode_execute, func_mode_install, func_mode_link):
Use func_lalib_unsafe_p where appropriate.
* (func_mode_execute): For the program wrapper, use
func_ltwrapper_p instead of func_lalib_p.
/bin/tcsh, trying to execute bourne shell helper scripts with

execute bits were lost by say, eeer, cvs, is gonna blow up in

itself, does not link against an uninstalled library. It appears
that this can happen if you are building a project where:
(1) there is a library
(2) there is an executable that does not, itself, link against
that library
In this case, notinst_deplibs is empty, and when the wrapper
script is loaded by libtool during ./libtool mode=install, there
is a check for "is notinst_deplibs empty". In this case, it is,
so libtool reports an error.
I don't think it is wrong to have a wrapper script for an exe that
*technically* doesn't need it. But instead of checking for
notinst_deplib nonempty as a proxy for "did wrapper script get
sourced into my environment properly" a different var should be
used.
* config/ltmain.m4sh (func_mode_install): set new variable
`generated_by_libtool_version' in wrapper script when using
libtool_install_magic. When verifying that wrapper script was
properly sourced, check that `generated_by_libtool_version' is
non-empty, instead of using notinst_deplibs.
ensure that import libraries don't get stripped.
* m4/libtool.m4 (_LT_SYS_DYNAMIC_LINKER): On Windows based hosts,
use postinstall_cmds to strip DLL (not import lib!) when symbol
stripped installation was requested.
pass. When the output wrapper script is not in the current
directory, we can not use an rpath which is relative to the
current directory. Use an absolute path instead.
to escape $ properly in combination with double_quote_subst.
(func_quote_for_eval): Four space indent margin for functions!
(func_quote_for_expand): Use $sed_double_backslash.
(func_show_eval): New function that echos an escaped but variable
expanded command, and then evaluates it.
from the match character set.
(double_quote_subst): Ditto.
* lib/general.m4sh (sed_quote_subst): Ditto.
(double_quote_subst): New variable, copied from
m4/libtool.m4. Much the same as sed_quote_subst, but variable
references are not quoted.
(func_quote_for_eval): Given any $foo; $bar and
$foo must be identical after the following commands:
func_quote_for_eval "$foo"
eval "bar=$func_quote_for_eval_result"
(func_quote_for_expand): In a similar vein to to func_quote_for_eval,
except that variable expansions are not protected when quoting the
command for subsequent display.
* config/ltmain.m4sh: Factor away use of $sed_quote_subst now that
it has been subsumed into func_quote_for_eval.
(func_mode_link): Instead of `2004-10-14 Peter O'Gorman' below,
use func_quote_for_expand so that ${wl} is expanded properly in
the $show expression.
