6f38107f80 Remove the support for C++ namespace cleanliness; it was 
causing more problems than it was curing, since it didn't work

for a proper C++ parser.

of C++, as it's treated like C now.
* src/bison.simple (YYSTD): Remove.

Treat C++ just like Standard C instead of trying to support
namespace cleanliness.
