- parser::report_error() calls only sax->parse_error(). For a SAX parser
whose parse_error() is static, as in unit-disabled_exceptions.cpp,
Visual Studio 2015 then reports the parameter as unreferenced (C4100),
which /WX turns into an error.
- The variadic concatenated() helper in unit-sax_parse.cpp made Visual
Studio 2015 fail with an internal compiler error (C1001). It now takes
an initializer list of byte vectors.
