18// The header <exception> contains low-level functions that interact
19// with a compiler's exception-handling mechanism. It is assumed to
20// be supplied with the compiler, rather than with the library, because
21// it is inherently tied very closely to the compiler itself.
22
23// On platforms where <exception> does not exist, this header defines
24// an exception base class. This is *not* a substitute for everything
25// in <exception>, but it suffices to support a bare minimum of STL
26// functionality.
