(warn_strict_null_sentinel): Define. (check_function_sentinel): Check for null_node as valid sentinel too. * c-common.h (c_tree_index): Added CTI_NULL. (null_node) Define global_tree[CTI_NULL]. (warn_strict_null_sentinel): Declare. * c-opts.c: (c_common_handle_option): Handle -Wstrict-null-sentinel. * c.opt: (Wstrict-null-sentinel): New C++ option. * doc/invoke.texi (C++ Options): Document -Wstrict-null-sentinel. * cp-tree.h (cp_tree_index): Remove CPTI_NULL, to be defined in C common frontend. (null_node): Remove. * lex.c (cxx_init): Move null_node initialisation to C common frontend. * g++.dg/warn/sentinel.C: New testcase for __null sentinels added.
