+	* ltmain.sh.in (echo): Change test to one that uses printf.
+	This works on AIX, which has the same problems that Solaris does,

 	* ltmain.sh.in (link): Make sure that compile_command and
  	finalize_command are always evaled.  Quote any unknown linker
  	flags we need to pass through.
+	(compile): Use quoting for flags we pass.
+	(echo): I hate Sun!  The /usr/bin/echo on Solaris handles
+	backslash sequences, which makes it impossible to do backslash
+	quoting using echo and sed.  So, we search for an echo that obeys
+	the `echo '\t'` = '\t' equality.  Then we use `$echo' everywhere
+	in ltmain.sh.
+	Put tabs back into the ${IFS= 	} sequences.  Emacs untabify is
+	libtool bane.
 
 	* ltconfig.in: Quote all variable values that may contain
 	metacharacters creating the libtool script.  This provides

 * Suppress duplicate compiler output during `compile' mode.
 * New `execute' mode to support debugging uninstalled libtool
   libraries and executables.
+* New quoting code to robustly handle any metacharacters passed in

 * Deleted `dlname' mode.  Dlopen applications should only use the
   runtime search method described in (libtool)Finding the dlname.
 * Experimental support for dynamically loaded modules, even on

 For next public release:
 ************************
 
+* #@%$ing SUN makes their Solaris /usr/bin/echo always interpret
+backslashes, so:
+    var='\n'
+    newvar=`echo "$var"`
+    test "$var" = "$newvar"
+returns false.  We need to detect this, and use the other
+echo (/usr/ucb/echo).

 * Document `execute' mode, and the experimental nature of -dlopen and
 -dlpreopen.
