operation of libtool (neither would work alone). First, there is
a new feature that allows libraries to preopen modules. This
entails a backwards incompatible change to the libltdl API for
separating out the preloaded symbol lists by owner. Second, in
the tradition of "eating our own dogfood", libltdl now preloads
its own dlloaders. The internal API for dlloaders has also had to
change in a backwards incompatible way in support of the new
library preloading feature. If you don't use preloaded libraries,
you needn't change your project sources, though you will need to
recompile against the new libltdl. The API changes are mostly
confined to dlloaders, so you probably needn't worry about those
(unless you have written a custom loader that you want libltdl to
use):
* configure.ac (AC_CONFIG_FILES): Add libltdl/loaders/Makefile.
* libltdl/configure.ac (AC_CONFIG_FILES): Add loaders/Makefile.

symbols to bootstrap the loader chain.

to load any other preloaded dlloaders.
(lt_dlloader_add): Simplify parameter list. Populate new
fields. Chain new loaders according to priority field.
* libltdl/ltdl.h (lt_dlsymlist): Add a new originator field.

Applications should assume that the native dlopen is NOT

* configure.ac: Invoke LT_LANG for each desired supported language.
* doc/libtool.texi: Remove documentation for the LT_INIT options,
rewrite LT_LANG documentation.
There was no clean separation of abstraction layers in libltdl.
The first step in fixing this is to factor out the memory
management abstraction, making a start on removing promiscuity
from the underlying portability layer:
* doc/libtool.texi (Libltdl interface): Remove lt_dlmalloc,
lt_dlrealloc and lt_dlfree references. The memory management
layer used by libltdl is now private.
* libltdl/lt_system.h: New installed header for system portability
abstraction.
* libltdl/ltdl.h: Use it.
* libltdl/lt__alloc.c, libltdl/lt__alloc.h: New module above
system portability layer to abstract ltdl's memory management.
* libltdl/ltdl.c: Use lt__alloc.h.

Removed in favour of...
(lt__strdup, lt__memdup, MALLOC, REALLOC, FREE): ...these calls
from libltdl/lt__alloc.h. Changed all callers.
(rpl_argz_append, rpl_argz_create_sep, rpl_argz_insert): As part
of the portability layer, these functions no longer use libltdl
memory management API.
(free_vars): Factored out.
(LT_DLMEM_REASSIGN): While redoing memory handling, renamed...
* libltdl/lt__alloc.h (MEMREASSIGN): ...to this.
* libltdl/Makefile.am (AUTOMAKE_OPTIONS): Let automake track
dependencies automatically.
(pkgincludedir): Override from parent package's setting.
(pkginclude_HEADERS): Install lt_system.h.
(libltdl_la_SOURCES): Add new files.
* NEWS: Updated.
