1) It enables library developers to write code that can run in both
environments.

2) It enables users of libraries that throw by boost::throw_exception
to write programs targeting exception-free environments.

3) It enables the rest of the Boost Exception functionality:
exception_ptr and transporting arbitrary data in exception objects.

Note that in 2) the program itself is specifically designed to target
exception-free environments, the developer being aware of the exact
conditions under which libraries call boost::throw_exception.
