--  This version of Ada.Exceptions fully supports Ada 95 and later language
--  versions.  It is used in all situations except for the build of the
--  compiler and other basic tools. For these latter builds, we use an
--  Ada 95-only version.

--  The reason for this splitting off of a separate version is to support
--  older bootstrap compilers that do not support Ada 2005 features, and
--  Ada.Exceptions is part of the compiler sources.
