- // This header exists solely for portability. Normally it just includes
- // the header <exception>.
- // 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.
