-       * configure.in: Reorganize handling of *-*-gnu*, to share target
-       specific make details with Linux.  Update comments to clarify
-        the distinction between GNU/Linux and GNU/Hurd.
        * config/t-gnu (LIBGCC1, CROSS_LIBGCC1, CRTSTUFF_T_CFLAGS,
        TARGET_LIBGCC2_CFLAGS): Remove.  We now use the settings from
        config/t-linux for the Hurd.
