The attached patch wraps PyObject_GetAttrString and
PyObject_HasAttrString in internal functions which have const
qualifier for the second argument. This is required because these
functions were missing the const qualifier in Python-2.4.

        * python/python-internal.h (gdb_PyObject_GetAttrString)
        (gdb_PyObject_HasAttrString): New inline function definitions.
        * py-value.c (get_field_flag): Remove the now unnecessary cast to
        (char *) of the second argument to PyObject_GetAttrString.
