    extension to some lists of object files passed to the linker;
    general cleanup of the command text echoed during execution.

    from hard_frame_pointer_rtx.

    * expr.c (expand_builtin, case BUILT_IN_FSQRT): Don't use
    asterisk in name of `errno'.

    stack for TARGET_EXPRs to the CLEANUP_POINT_EXPR code and change
