Backport from upstream Libtool: 2007-10-12 Eric Blake <ebb9@byu.net> Deal with Autoconf 2.62's semantic change in m4_append. * ltsugar.m4 (lt_append): Replace broken versions of m4_append. (lt_if_append_uniq): Don't require separator to be overquoted, and avoid broken m4_append. (lt_dict_add): Fix typo. * libtool.m4 (_LT_DECL): Don't overquote separator.
