Subject: libstdc++: Rename _CwFixedValue::_S_type member
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=39c003c0ecd4fcaf801e923b85e921327fd0d5d3;p=thirdparty%2Fgcc.git

libstdc++: Rename _CwFixedValue::_S_type member

Rename _S_type to __type as it's not a static member.

Also rename _Tp to _Xv because it's not a type.

libstdc++-v3/ChangeLog:

	* include/std/type_traits (_CwFixedValue::_S_type): Rename to
	__type.
	(constant_wrapper): Rename template parameter in declaration to
	match later definition.
