    	(StdMapPrinter.children): Use type's const method.
    	* python/python-type.c (typy_const): New function.
    	(typy_volatile): Likewise.
    	(typy_unqualified): Likewise.
    	(type_object_methods): Add const, volatile, unqualified.
    gdb/doc
    	* gdb.texinfo (Types From Inferior): Document const, volatile,
    	and unqualified methods.
