            Bug ID: 60263
           Summary: C++11 header "cuchar" is missing
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gccbug at suremail dot info

The header file is missing and the macros __STDC_UTF_16__ and __STDC_UTF_32__
are not defined (even when uchar.h is included). Please fix for standard
compliance.

In <http://gcc.gnu.org/ml/gcc-patches/2011-08/msg01524.html>, Jason said 
he'd raised the issue of whether C++11 really should be different from C11 
regarding those macros being in a header rather than predefined; I don't 
know what the conclusion was.  If it was that the header really should 
define the macros for C++ rather than the compiler, sending a patch to 
glibc's <uchar.h> would be a good idea (but of course libstdc++ still 
needs <cuchar>).

This reminds me, that there exists a corresponding LWG issue for this:
