This does not apply (afaics)
We never use 'char' for char_type.
My bad. I should have read the patch.
#if defined(HAVE_WCHAR_T) && SIZEOF_WCHAR_T == 4
// Prefer this if possible because GNU libstdc++ has usable
// std::ctype<wchar_t> locale facets but not
// std::ctype<boost::uint32_t>. gcc older than 3.4 is also missing
// usable std::char_traits<boost::uint32_t>.
typedef wchar_t char_type;
#else
typedef boost::uint32_t char_type;
#endif
A quick google search for 'signed wchar_t' turns up this:
