 // The header <exception> contains low-level functions that interact

 // with a compiler's exception-handling mechanism.  It is assumed to

 // be supplied with the compiler, rather than with the library, because

 // it is inherently tied very closely to the compiler itself.

 // On platforms where <exception> does not exist, this header defines

 // an exception base class.  This is *not* a substitute for everything

 // in <exception>, but it suffices to support a bare minimum of STL

 // functionality.
