        m4             : system_.h macro.c 

Log message:
        * m4/system_.h (obstack_regrow): New macro.  Hopefully glibc will
        accept it someday.
        * m4/macro.c (expand_macro): Avoid referencing invalid memory.
        Handle nesting the argc obstack.
        (expand_token): Avoid unnecessary malloc.
        (collect_arguments): Copy name before invalidating it.
        (argc_stack, argv_stack): New variables.
        (m4_macro_expand_input): Initialize argc and argv stacks once per
        file, instead of once per macro.
