definition of lt_libltdlc_LTX_preloaded_symbols tagged with
__declspec(dllexport) in ltdl.c and one definition with an
initial value in libltdlcS.c. So, just say extern in ltdl.c.
Fixes the mdemo-exec.test for MinGW.
portable, and had problems with GNU make-3.80 at least. This
changeset pulls the installation rules for libtoolize's copy of
the libltdl sources out of libltdl/Makefile.am so that
ltdldatafiles is defined in the same Makefile that uses it. Also,
this makes a start at cleaning up libltdl/Makefile.am so that it
is useful in a package that uses `libtoolize --ltdl':
* libltdl/loaders/Makefile.am: Removed entirely.
* libltdl/Makefile.am (dlopen.la, dld_link.la, dyld.la)
(load_add_on.la, loadlibrary.la, shl_load.la): All built from here
now that the loaders submake has gone.
(show-ltdldatafiles): Removed. No longer required.
(ltdldatadir, ltdldatafiles, install-local): Moved from here...
* Makefile.am (ltdldatadir, ltdldatafiles, install-local): ..to
here.
(libtoolize): Substitute $(ltdldatafiles) directly without calling
make to get the value from libltdl/Makefile.
for copying files correctly from the source tree, we must know
exactly which files should be copied by the --ltdl option to avoid
accidentally picking up compilation objects and other noise when
$builddir == $srcdir:
* libltdl/loaders/Makefile.am (ltdldatadir, ltdldatafiles)
(install-data-local): Removed...
* libltdl/Makefile.am (ltdldatafiles): ...and consolidated here.
(show-ltdldatafiles): New rule...
* Makefile.am (ltdldatafiles, libtoolize): ...used to substitute
exactly which files are installed by libtoolize --ltdl.
(edit): Move pkgvmacro_DATA substitution expression...
(libtoolize): ...to here.
* libtoolize.m4sh: Use func_copy_some_files() instead of
func_copy_all_from_path() to copy the --ltdl option installed
files.
(pkgvltdldirs): New path variable to search for files installed by
--ltdl option.
(func_massage_pkgvltdl_files): New function to calculate the list
of ltdl installation files.
format with the `o' flag in create mode.
Set the umask to 0 when untarring to avoid copied files taking
their mode from the installer's umask.
* libltdl/loaders/Makefile.am (install-data-local): Ditto.
* libtoolize.m4sh (func_copy_cb): Ditto.
Ignore errors from failed `cd' in the tar processes, since we
may be running in dryrun mode.

Don't remove the destination directory, since that interacts badly
with the multi-Makefile installation.
* libltdl/loaders/Makefile.am (install-data-local): Ditto.
libraries that will be used as modules -- the pic objects are
built normally, and are not expected to resolve all their symbols
until they are linked into a library; convenience libraries are
then rolled using 'ar' and 'ranlib' (or equivalent) which also do
not check whether symbols are resolved. We now build each of the
loaders as a convenience library module under these assumptions,
and link libltdl.la with selected modules, at which time all of
the symbols *are* resolved:
* TODO: Remove item addressed by this changeset.
* libltdl/Makefile.am (lib_LTLIBRARIES): Remove libdlloader.la.
(libdlloader_la_SOURCES): Declaration removed. Changed all
clients. Source files..
(libltdl_la_SOURCES): ...added back in here.
(libdlloader_LDFLAGS, libdlloader_la_LIBADD): Removed.
(libltdl_la_LIBADD): Remove libdlloader.la; add $(LTLIBOBJS).
* libltdl/loaders/Makefile.am: Removed all references to
libdlloader.la.
`libtoolize --ltdl --copy' is pointless if they are not preserved
from the libtool source tree at install time:
* libltdl/Makefile.am, libltdl/loaders/Makefile.am
(nobase_ltdldata_DATA): Renamed to...
(ltdldatafiles): ...this.
(install-data-local): New rule to install libltdl tree with tar to
preserve timestamps.

copying and concatenation for improved security.
* libltdl/Makefile.am: Optionally build source files

* m4/ltdl.m4 (LTDL_INIT): Add checks for strlcat and strlcpy.
