+ Much as we have tried not to make it the callers' responsibility
+ to maintain an lt_dlrealloc function pointer, it is too difficult
+ to implement realloc as malloc/memcpy/free without knowing the
+ size of the original block. rpl_realloc has been deprecated since
+ 2002-10-30, but kaffe has real failures with that so it's time to
+ bite the bullet. Caller gets to maintain lt_dlrealloc:
+
+ * NEWS (1.5.1): Updated.
+ * libltdl/ltdl.c (LT_DLREALLOC): Use lt_dlrealloc so the user can
+ update the function pointer to match lt_dlmalloc.
+ (lt_emalloc): Use lt_dlrealloc rather than hardcoding realloc.
+ * doc/libtool.texi (Libltdl interface): Describe lt_dlrealloc now
+ that it too has become part of the exported interface to libltdl.

* libltdl/ltdl.c (dyld): Save the error from the first lookup
to report in lt_dlerror(). Otherwise the error is always
"Symbol _foo not in /usr/lib/libSystem.dylib".
* ltmain.in: search libraries in the order of preference, rather
than picking .la's even if they're in a less preferred directory.

*destination* ptr to decide how much to copy. This
sometimes results in out-of-bound accesses which cause
segfaults. This is a quick hack for now; we may want
- something cleaner later. (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?

@cindex mode, install
In @dfn{install} mode, libtool interprets most of the elements of

@code{cp}, or a BSD-compatible @code{install} program.
The following components of @var{mode-args} are treated specially:
@table @samp
@item -inst-prefix @var{inst-prefix-dir}
When installing into a temporary staging area, rather than the
-final @var{prefix}, this argument is used to reflect the
+final @var{prefix}, this argument is used to reflect the
temporary path, in much the same way @code{automake} uses
@var{DESTDIR}. For instance, if @var{prefix} is @code{/usr/local},
but @var{inst-prefix-dir} is @code{/tmp}, then the object will be
-installed under @code{/tmp/usr/local/}. If the installed object

is a libtool library, then the internal fields of that library
will reflect only @var{prefix}, not @var{inst-prefix-dir}:
libdir='/tmp/usr/local/lib'
@end example
-@code{inst-prefix} is also used to insure that if the installed
-object must be relinked upon installation, that it is relinked

In truth, this option is not really intended for use when calling
libtool directly; it is automatically used when @code{libtool --mode=install}
