compatible. Instead, revert to the old way of doing things with
an array of symbol name vs. address, and adding the originator as
the first symbol but with a NULL address:

NULL address symbol.

language. Running the tests over a broken compiler can corrupt
these values, when there is no C++ compiler for example, so we
skip most of the tests in those cases.

CVS autoconf, otherwise pdksh chokes on some nested escaped quotes

protects libtool and libtoolize:

* ltmain.in: Ditto.

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.

the loaders directory contents.

to load any other preloaded dlloaders.

fields. Chain new loaders according to priority field.

is discovered.
