To safely use a non-literal fist argument to 'test', you must
always prepend a literal non-'-' character, but often the second
operand is a constant that doesn't begin with a '-' already, so
always use 'test a = "$b"' instead of the noisy 'test "X$b" = Xa'.

At some point we were supporting some undetermined `broken
make', as evidenced by having carried the following code since
2003:
## use @LIBLTDL@ because some broken makes do not accept
## macros in targets, we can only do this because our LIBLTDL
## does not contain $(top_builddir).
@LIBLTDL@: $(top_distdir)/libtool \
...
However, we've also had *many* cases of macros in targets for
just as long, so most likely we never fully supported makes
allegedly broken in this way. As of this release, we explicitly
no longer support make implementations that do not accept macros
in targets.

In addition to moving the autoconf auxiliary script directory
into the place expected by GNU developers ($top_srcdir/build-aux)
we also simplify libtoolize somewhat by having libltdl use
whatever directory was specified by the parent project. This is
much more flexible, allows libltdl client projects to also use a
single canonical `$top_srcdir/build-aux' auxiliary script
directory, and maintains backward compatibility with existing
projects that wish to continue using $ltdl_dir/config.
* libltdl/config: Moved whole directory from here...

tests/depdemo/configure.ac, tests/f77demo/configure.ac,
tests/mdemo/configure.ac, tests/pdemo/configure,ac,
tests/tagdemo/configure.ac: Remove calls to AC_LIBTOOL_TAGS,
the default 'auto-lang' mode now does the right thing.
* doc/libtool.texi (The LT_INIT macro): Add documentation for
new LT_INIT options and the LT_LANG macro, replacing the old
documentation of AC_LIBTOOL_TAGS which is no more.
* NEWS: Updated.
`configure.ac' to be more like AC_INIT and accept a space
delimited list of options. Instead of calling `AC_LIBTOOL_DLOPEN;
AC_PROG_LIBTOOL', we now recommend `LT_INIT([dlopen])':
* m4/libtool.m4 (AC_PROG_LIBTOOL, _AC_PROG_LIBTOOL)
(AC_LIBTOOL_SETUP): Removed. Added AU_DEFUNs.
(LT_INIT): Replace with an Autoconf like interface which accepts a
version number as a minimum required libtool release at configure
time.
* m4/ltoptions.m4: New file inspired by automake/m4/amoptions.m4,
which additionally flags an error if the configuring libtool
macros are not new enough according to LT_INIT.
(LT_OPTION_DEFINE): New macro to declare option handlers.
(dlopen, win32-dll, shared, disable-shared, static)
(disable-static, fast-install, disable-fast-install, pic-only)
(no-pic): Newly LT_OPTION_DEFINEd option handlers that use...
(_LT_ENABLE_SHARED, _LT_ENABLE_STATIC, _LT_ENABLE_FAST_INSTALL)
(_LT_WITH_PIC, _LT_WIN32_DLL): New macros to handle
LT_LIBTOOL_INIT options...
* m4/libtool.m4 (AC_ENABLE_SHARED, AC_ENABLE_STATIC)
(AC_ENABLE_FAST_INSTALL, AC_LIBTOOL_DLOPEN, AC_LIBTOOL_WIN32_DLL):
...to replace these user interface macros, now defined as
AU_DEFUNs.
(AC_DISABLE_SHARED, AC_DISABLE_STATIC, AC_DISABLE_FAST_INSTALL):
Removed. No longer required with LT_INIT_LIBTOOL interface.
Added AU_DEFUNs.
(AM_ENABLE_SHARED, AM_DISABLE_SHARED, AM_ENABLE_STATIC)
(AM_DISABLE_STATIC): Changed AU_DEFUNs to match new interface.
(_LT_SETUP): Internal to LT_INIT, replaces AC_LIBTOOL_SETUP.
* m4/lt~obsolete.m4 (AC_LIBTOOL_SETUP, _AC_PROG_LIBTOOL)
(_LT_PROG_LTMAIN): More AC_DEFUNs that have been retracted.
* configure.ac: Use new interface.
* doc/libtool.texi: Document new interface.
* NEWS: Updated.
tests/depdemo/configure.ac, tests/f77demo/configure.ac,
tests/mdemo/configure.ac, tests/mdemo2/configure.ac,
tests/pdemo/configure.ac, tests/tagdemo/configure.ac: Declare just
the tags we need using AC_LIBTOOL_TAGS, reducing the size of the
configure script by 50% in most cases.
then tweak the results by hand:
* m4/libtool.m4 (AC_PROG_LD): In common with all the other
AC_PROG_ macros, AC_SUBST the discovered LD.
(AC_PROG_NM): Similarly for NM.
(LT_AC_PROG_SED): Similarly for SED.
* configure.ac: No need to SUBST NM and LD manually any more.
(AC_PREREQ): Conservatively downgrade from 2.59 to 2.54.
* tests/cdemo/configure.ac, tests/demo/configure.ac,
tests/depdemo/configure.ac, tests/f77demo/configure.ac,
tests/mdemo/configure.ac, tests/mdemo2/configure.ac,
tests/pdemo/configure.ac, tests/tagdemo/configure.ac: Ditto.
* m4/libtool.m4 (AM_PROG_LIBTOOL, AM_ENABLE_SHARED,
AM_ENABLE_STATIC, AM_DISABLE_SHARED, AM_DISABLE_STATIC,
AM_PROG_LD, AM_PROG_NM): AU_DEFUN these macros so autoupdate can
use the newer definitions.
