We will be providing libguile-ltdl, and libguile will link against
it.  We will provide no headers for any of the libguile-ltdl
functionality, but dynamic-link and friends will be using it.

This has already been done, though I haven't finished committing the
second half of the work that mvo started, and so far it fixes the
problems listed below (most reported upstream in November of last year
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=120169&repeatmerged=yes).

We will also probably be adding support for /etc/ld.so.conf and
/usr/local/lib/ on the platforms where we already know it makes sense.

	* guile-ltdl.c: Remove custom realloc. (#define rpl_realloc
	realloc).  You can't define realloc like this unless you also
	define malloc.  This is a quick hack for now; we may want
	something cleaner later.
	(memcpy): coerce ptrs to (char *) before copying characters
	through them -- I can't recall for sure, but I believe this was
	causing an overrun error at times.
	(realloc): commented out -- as mentioned above, you can't define
	your own malloc unless you know enough about the malloc in use to
	be able to tell how big the src ptr is.  The disabled code
	incorrectly used the *destination* ptr to decide how much to copy.
	This sometimes results in out-of-bound accesses which cause
	segfaults.
	(tryall_dlopen_module): check to be sure (dirname_len > 0) before
	testing first character against '/'.
	(try_dlopen): check for feof(file) in read loop -- otherwise
	infloop?
	(scm_lt_dlopenext): remove unused variable file_found.

2002-10-04  Marius Vollmer  <mvo@zagadka.ping.de>

	* guile-ltdl.c: Renamed all exported functions and variables to have a
	"scm_lt_" prefix.
	(try_dlopen): Set newhandle to null when try_all_dlopen failed.
	(scm_lt_dlopenext): Reverse test of "file_not_found()".
	Previously, we would stop searching when the file wasn't found
	yet, while we should continue in that case.
