#ifndef _LIBCPP_UCHAR_H
#   error <cuchar> tried including <uchar.h> but didn't find libc++'s <uchar.h> header. \
          This usually means that your header search paths are not configured properly. \
          The header search paths should contain the C++ Standard Library headers before \
          any C Standard Library, and you are probably using compiler flags that make that \
          not be the case.
