  //@DESCRIPTION: Provide types, in the 'bsl' namespace, equivalent to those
  // defined in the corresponding C++ standard header.  Include the native
  // compiler-provided standard header, and also directly include Bloomberg's
  // implementation of the C++ standard type (if one exists).  Finally, place the
  // included symbols from the 'std' namespace (if any) into the 'bsl' namespace.
