| C++ builtins go in both std and global namespaces.

This patch (at least, as described) makes wrong assumptions.
For example, <string.h> declares std::strlen and ::strlen whereas
<cstring> declares only std::strlen.  A name 'foo' declared by <xxx.h>
behave as if it were declared

    namespace std
    {
       // 'foo' declaration goes here
    }

    using std::foo;

The same should apply to builtins.  And I think builtin names should
begin with a double underscore.  Why do you want to remove them?
