	PR c++/86608 - reading constexpr volatile variable.
	* constexpr.c (potential_constant_expression_1): Check want_rval
	instead of checking if we have a decl.
	* decl2.c (decl_maybe_constant_var_p): Don't consider volatile
	constexpr variables as maybe constant.

	* g++.dg/cpp0x/constexpr-volatile2.C: New test.
	* g++.dg/cpp0x/pr65327.C: Add dg-error.
