+       Extend AC_LIB_LINKFLAGS to the situation of several libraries provided
+       by a single package.
+       * m4/lib-link.m4 (AC_LIB_FROMPACKAGE): New macro.
+       (AC_LIB_LINKFLAGS_BODY): Use the information stored by
+       AC_LIB_FROMPACKAGE. Use AC_ARG_WITH instead of AC_LIB_ARG_WITH.
+       Reported by Sam Steingold <sds@gnu.org>.

        * build-aux/bootstrap (version_controlled_file): Adapt for SVN
