+Subject: libtool: mitigate the $sed_quote_subst slowdown
+
+When it is reasonably possible, use shell implementation for
+quoting.
+
+References:
+http://lists.gnu.org/archive/html/libtool/2015-03/msg00005.html

+https://debbugs.gnu.org/cgi/bugreport.cgi?bug=20006
+
+* gl/build-aux/funclib.sh (func_quote): New function that can be
+used as substitution for '$SED $sed_quote_subst' call.
+* build-aux/ltmain.in (func_emit_wrapper): Use func_quote instead
+of '$SED $sed_quote_subst'.
+(func_mode_link): Likewise.
+* NEWS: Document.
+* bootstrap: Sync with funclib.sh.
+
