+	* ltmain.sh.in (install): Relink if hardcode_action is `relink',
+	rather than using complex conditionals based on the other
+	hardcode variables.
+
+	* ltconfig.in (hardcode_action): Set to `relink', not `immediate',
+ 	if we can only hardcode existing directories.  Rearrange
+ 	conditionals to make the intent clearer, otherwise this can be one
+ 	hellish piece of code for the already-dizzy libtool maintainer.

+	* replfunc.m4: Delete from the distribution.  Documentation now
+	describes how to set LTALLOCA and LTLIBOBJS in your own
+	configure.in.
+
+	* ltmain.sh.in (link): Make sure a libtool library only counts as
+	a shared library if its library_names are non-null.
+	Use timestamps for .lo's when PIC is turned off, rather than
+	symlinking to the real object.  This helps invalid mixtures of PIC
+	and non-PIC to fail.

@@ -1383,35 +1387,33 @@ The Autoconf package comes with a few macros that run tests, then set a

 necessary to use corresponding names for libtool objects.
 
-So, included with libtool are convenience macros that do this kind of

+Unfortunately, the most recent version of Autoconf (2.12, at the time of

+these variables.  So, if you depend on them, use the following code
+immediately before the call to @code{AC_OUTPUT} in your
