The parser is a patched GCC 4.2 so there is no C++11 support.

As a quick hack, try defining -Dconstexpr= -Dnoexcept= on the
command line.

We distribute patched copies of system headers to work around
such limitations (and have done so even before C++11 to handle
other compilers' extensions).  If one places a hacked copy of
this header in GCC_XML/Support/GCC/4.7/bits it will override
the system one.

One of these solutions will need to be builtin upstream.  You
could fork on Github from https://github.com/gccxml/gccxml
and submit a pull request.

Thanks,
