Hi!

I'm not 100% sure, but I *think* that this patch

	2015-11-15  Jonathan Wakely  <jwakely@redhat.com>
	
		PR libstdc++/68353
		* include/bits/basic_string.h: Test value of _GLIBCXX_USE_C99_WCHAR
		not whether it is defined.
		* include/ext/vstring.h: Likewise.

uncovered errors like this:

Shows up when using a newly build compiler to build the
contrib/config-list.mk targets. So these targets probably need some
