        * symtab.c (symbol_natural_name): Call objc_decode_symbol.
        * objc-lang.c (objc_decode_symbol): New function.
        (demangle_obj): Leave category parentheses even if there is no
        category name.  Fix for gnu coding standards.
        * objc-lang.h: (objc_decode_symbol): Declare.
