The C++ standard library should not be introducing names into the global
namespace.  I would consider that an implementation flaw.

Granted, the name '_Bool' is in the name space (not namespace) reseved
for the implementation, so removing it from stdbool.h should also fix the
symptom, but I would consider backward compatibility with existing software,
both that which uses stdbool.h and that which uses other nonconfirming _Bool
definitions.

I think moving the type_traits names, all of them, into __gcc_cxx:: is worth
doing regardless.
