Originally reported at
<a href="https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244035">https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244035</a>.
The FreeBSD people told me to report it here.
C++11 added the header file <cuchar> (a wrapper around the C header file
<uchar.h>). See <a href="https://en.cppreference.com/w/cpp/header">https://en.cppreference.com/w/cpp/header</a>
$ cat foo.cc
#if __cplusplus >= 201103
#include <cuchar>
#endif
$ c++ -c foo.cc
foo.cc:2:10: fatal error: 'cuchar' file not found
#include <cuchar>
