Subject: libstdc++: Add comment noting LWG 3617 support
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b200461e0f3bf6450ec1cf17b4036ff2033607dc;p=thirdparty%2Fgcc.git

libstdc++: Add comment noting LWG 3617 support

The resolution was implemented in r14-8752-g6f75149488b74a but I didn't
add the usual _GLIBCXX_RESOLVE_LIB_DEFECTS comment.

libstdc++-v3/ChangeLog:

	* include/bits/std_function.h: Add comment about LWG 3617 being
	supported.
