	* include/cpplib.h (cpp_callbacks): Add has_attribute.
	* internal.h (lexer_state): Add in__has_attribute__.
	* directives.c (lex_macro_node): Prevent use of __has_attribute__
	as a macro.
	* expr.c (parse_has_attribute): New function; (eval_token): Look for
	__has_attribute__ and route to parse_has_attribute.
	* identifiers.c (_cpp_init_hashtable): Initialize n__has_attribute__.
	* pch.c (cpp_read_state): Initialize n__has_attribute__.
	* traditional.c (enum ls): Add ls_has_attribute, ls_has_attribute_close;
	(_cpp_scan_out_logical_line): Attend to __has_attribute__.


gcc/c-family:

2014-11-10  Edward Smith-Rowland  <3dw4rd@verizon.net>

	* c-cppbuiltin.c (__has_attribute, __has_cpp_attribute): New macros;
	(__cpp_rtti, __cpp_exceptions): New macros for C++98;
	(__cpp_range_based_for, __cpp_initializer_lists,
	__cpp_delegating_constructors, __cpp_nsdmi,
	__cpp_inheriting_constructors, __cpp_ref_qualifiers): New macros
	for C++11; (__cpp_attribute_deprecated): Remove in favor of
	__has_cpp_attribute.
	* c-lex.c (cb_has_attribute): New callback CPP function;
	(init_c_lex): Set has_attribute callback.


gcc/testsuite:

2014-11-10  Edward Smith-Rowland  <3dw4rd@verizon.net>

	* g++.dg/cpp1y/feat-cxx11.C: Test new feature macros for C++98
	and C++11; Test existence of __has_cpp_attribute;  Test C++11
	attributes.
	* g++.dg/cpp1y/feat-cxx11-neg.C: Ditto.
	* g++.dg/cpp1y/feat-cxx14.C: Ditto and test for C++14 attributes.
	* g++.dg/cpp1y/feat-cxx98.C: Test new feature macros for C++98.
	* g++.dg/cpp1y/feat-cxx98-neg.C: Ditto.
	* g++.dg/cpp1y/feat-neg.C: Test that __cpp_rtti, _cpp_exceptions
	will be undefined for -fno-rtti -fno-exceptions.
