* raw-ltdl.c: merged changes from libtool 1.5. Looks like most of
our bugfixes have been incorporated upstream.
* upstream/ltdl.c: update to libtool 1.5 version.
* upstream/ltdl.c.diff: added.
* upstream/ltdl.h.diff: added.
* upstream/Makefile.am (ltdl.h.diff): cleanup temp files.
(ltdl.c.diff): cleanup temp files.
* upstream/.cvsignore: remove ltdl.c.diff and ltdl.h.diff -- these
should probably be in the source tree so we're more likely to
notice any unintentional changes, and so it's easier for people to
find the diffs.

* upstream/Makefile.am (ltdl.h.diff, ltdl.c.diff): Look for ltdl.h

-*-text-*-
This subtree contains a locally modified version of libltdl from
libtool.
guile-ltdl.h describes the interface that Guile actually uses.
guile-ltdl.c is the main source file which directly #includes
raw-ltdl.h and raw-ltdl.c
The two raw-* files are Guile's patched versions of the
upstream/ltdl.* files, the latter of which are the original libtool
source from which the current raw-* files are derived.
We use this unusual inclusion trick, along with a few modifications
to the raw-* files and some #defines in guile-ltdl.c to allow us to
use the upstream source with as few unnecessary changes as possible,
while still making all of the upstream symbols non-extern. This
means that libguile-ltdl *only* exports the few symbols that Guile
actually needs right now.
In general libguile-ltdl exports the needed libltdl functions and
data structures with scm_ prepended to them, so we have
scm_lt_dlinit, etc.
The upstream/* subdirectory contains the clean upstream source from
which the raw-ltdl.h and raw-ltdl.c files were derived, and an
automatically generated diff from the upstream. Note that during
the diff process we automatically remove a set of changes we've made
to the upstream source (mostly related to making all of the upstream
exports static) that are uninteresting outside of Guile.
We hope that taking these steps will make it easier to fold our
changes back into the main version of libltdl, and in fact, it looks
like most, if not all of our original serious bug fixes have been
incorporated upstream, leaving essentially only the scoping related
changes mentioned above in our filtered upstream/*.diff files.
The current upstream/* source is from libtool version 1.5.
