visibility set according to the underlying implementation.
Here, we add lt_dlopenadvise() to allow callers to request,
among other things, local or global symbol visibility from the
underlying dlloader:
* libltdl/ltdl.c (LT_DLRESIDENT_FLAG): Removed.
(LT_DLIS_RESIDENT): Use public is_resident info field.
(LT_DLIS_SYMLOCAL, LT_DLIS_SYMGLOBAL): New macros to test for
module symbol visibility status.
(tryall_dlopen): If vtable->module_open() was able to act on
either is_symlocal or is_symglobal hints, store that in
the handle flags.
(lt_dlopenadvise): New function that works like lt_dlopen(),
but accepts an advise type to determine whether to ask
dlloaders to change default symbol visibility.
(lt_dlopen, lt_dlopenext): Just call lt_dlopenadvise() with
the correct parameters.
(lt_dladvise_init, lt_dladvise_destroy): New functions to
initialize and destroy an advise type hint.
(lt_dladvise_ext, lt_dladvise_resident, lt_dladvise_local)
(lt_dladvise_global): Set hints on an advise type.
(openadvise): Factored out of lt_dlopenadvise.
(has_library_ext): Factored out of lt_dlopenadvise.
* libltdl/ltdl.h: Declare all of the above.
(lt_dlinfo): New fields for advise hints.
* libltdl/libltdl/lt_dlloader.h (lt_module_open): Add a new
advise parameter. Adjust all callers.
(lt_dladvise): New opaque type for advise hints.
* libltdl/libltdl/lt__private.h (lt__advise): Declare
contents of opaque lt_dladvise type.
* libltdl/libltdl/lt_error.h (CONFLICTING_FLAGS): New error
for attempts to have local and global symbol visibility at the
same time.
* libltdl/loaders/dld_link.c, libltdl/loaders/dyld.c,
libltdl/loaders/load_add_on.c, libltdl/loaders/loadlibrary.c,
libltdl/loaders/preopen.c, libltdl/loaders/shl_load.c: Adjust.
* libltdl/loaders/dlopen.c (RTLD_LOCAL, RTLD_GLOBAL): Try to
define these symbols if the system has equivalents.
(vmopen): If unable to act on a caller request to set symbol
visibility, then unset the relevant hints in the advise type.
* tests/lt_dladvise.at: New tests for the above.
* doc/libtool.texi (Libltdl Interface): Updated.
* NEWS: Updated.

* tests/stresstest.at: Test `-no-install'.
* THANKS: Update.

Point the user to the doc/notes.txt file. In the examples, use
`gmake' throughout to make it more obvious. Explain simpler way
to run both testsuites and either one. Referring to individual
tests needs the `tests/' prefix.
* README.alpha: Likewise.
* doc/notes.texi: Likewise, document need for GNU make.
Comment out the FreeBSD make issue for now.

(When tests fail, Troubleshooting): Mention how to pass options
to the new test suite.
* tests/tagdemo/README: Fix description.
* tests/template.at: Only skip those tests failing on Darwin
if `-flat_namespace' is used by libtool. In that case, SKIP
at the end. Analysis by Peter O'Gorman.
<compiler_needs_object>: New tag variable. Default to `no'.
(_LT_LINKER_SHLIBS) [ linux ]: Set it to yes for Sun C 5.9.
(_LT_LANG_CXX_CONFIG): Also default it to `no'.
[ linux ]: Set it to `yes' for Sun C++ 5.9.
* libltdl/config/ltmain.m4sh (func_mode_link): If we link
no objects but only convenience archives into a library,
force expansion if `compiler_needs_object' is yes.
For creating a linker input filelist due to long cmdline,
extract the first object if `compiler_needs_object' is yes.
* doc/libtool.texi (libtool script contents): Document it.
Fixes test failures of Sun compilers on GNU/Linux.
Report by Terry D. Dontje.
nonrecursive mode, a config header is now required.
* libltdl/argz.c: Remove check for HAVE_CONFIG_H, to conform
to gnulib's policy of including config.h unconditionally.
(libtool script contents) <CC>: Specify more precisely as the
compiler of the current tag.
<LTCC, LTCFLAGS, build, build_alias, build_os, host_alias,
host_os, macro_version, macro_revision, max_cmd_len>:
Document these variables.
prefix and suffix of a library may differ.
(Using libtool, Creating object files, Linking libraries):
Remove last documentation traces of the age when `foo.lo' was
the PIC object file and not the `libtool object' text file.
(libtool script contents) <compiler_o_lo>: Remove description
of this variable. It was removed from libtool in 1.5 times.
For nonrecursive mode, add to include_HEADERS as well.
* doc/libtool.texi (Invoking libtoolize, Distributing libltdl),
tests/nonrecursive.at: Adjusted, and removed TABS from .texi.
use in non-recursive libltdl installations.
* bootstrap: Adjust.
* Makefile.am: include it.
(libltdl/Makefile.am): Adjust to build from the new
libltdl/Makefile.inc.
(SUBDIR_LIBOBJS): Renamed from this...

and --subproject. Install the appropriate files with --ltdl
according to the selected mode.
(func_scan_files): If --subproject, --recursive or --nonrecursive
options were not given, use the value from LT_CONFIG_LTDL_DIR; if
a mode was given, and there is also an argument to
LT_CONFIG_LTDL_DIR, ensure they are the same.
* NEWS: Updated.
interface.
(LT_CONFIG_LTDL_DIR): New macro to centralise setting the
subdirectory used for libltdl.
(LTDL_CONVENIENCE): Continue backwards compatibility support for
declaring the libltdl source subdirectory with an argument, but
defer to LT_CONFIG_LTDL_DIR.
(AC_LIBLTDL_CONVENIENCE): Adjust to upgrade to the new style.
(LTDL_INSTALLABLE, AC_LIBLTDL_INSTALLABLE): Ditto.
(LTDL_INIT): lt_ltdl_dir is set by LT_CONFIG_LTDL_DIR now, and
even `./' needs trailing slashes trimming! If the user didn't
upgrade their configure.ac yet, call LT_CONFIG_LTDL_DIR for them.
* libtoolize.m4sh (func_scan_files): If --ltdl option is given
without a directory argument, use the value from
LT_CONFIG_LTDL_DIR; if the argument is given, and there is also a
value in LT_CONFIG_LTDL_DIR, ensure they are the same.
* libltdl/configure.ac: Use it.
* NEWS: Updated.
with module visibilty when linked with programs written for the
old API.
(lt_dlinterface_register): New name.
* Makefile.am (VERSION_INFO): Bumped.
* doc/libtool.texi (User defined module data): Updated.
Symbols in "pick any" sections are not global. Use
awk, not sed, in the global_symbol_pipe so that keeping
track of sections is easier.
* doc/libtool.texi (libtool script contents): Update to hint
at new findings concerning "pick any" sections.
(LT_PATH_NM): If nm is not found on the path, look for
dumpbin. Then check if $NM responds as dumpbin would
and if not, assume the name lister is BSD nm compatible.
(_LT_CMD_GLOBAL_SYMBOLS): If the name lister uses the
dumpbin interface, adjust the test to find a working
global_symbol_pipe.
* doc/libtool.texi: Document $NM to possibly be MS
dumpbin compatible, and also document the format of the
relevant output from MS dumpbin.
libtool before config.status.
(_LT_CONFIG_COMMANDS): If LT_OUTPUT has been invoked, then
generate code in config.status to call config.lt instead of
generating libtool directly.

will be overwritten by the installation, and perform a manual
installation of $(aclocalfiles) to preserve timestamps.
(install-exec-hook): Removed. No need to make versioned links.
(uninstall-hook): No need to remove versioned links, but now we
need to manually remove the manually installed $(aclocalfiles).

ACLOCAL_AMFLAGS for versioned libtool installations.
* NEWS: Remove parallel installation item.
files generated in doc and tests already lived in
$top_srcdir/Makefile.am, along with proxy rules in sub-Makefiles,
this changeset consolidates almost everything into the top
Makefile.am, simplifying things considerably:
* doc/Makefile.am, tests/Makefile.am: Removed. All rules moved...
* Makefile.am: ...to here and adjusted to run from $top_builddir.
Some reformatting to group rules and declarations by purpose, and
simplify with respect to removing much of the make recursion.
Add `doc/PLATFORMS', `doc/fdl.texi' and `doc/notes.texi'.
`defs.in' and `defs.m4sh' are in directory `tests'.
(uninstall-hook): Don't forget to uninstall libtoolize's libltdl
source tree.
