2013-04-22  Paolo Carlini  <paolo.carlini@oracle.com>

	N3669
	* include/std/complex (complex<float>::real, complex<float>::imag,
	complex<double>::real, complex<double>::imag,
	complex<long double>::real, complex<long double>::imag): Declare
	as const member functions.
	* include/std/type_traits (integral_constant<>::operator value_type):
	Likewise.
