VMS Help CC, Messages, NESTEDENUM  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        The type "<type>" is declared nested within
                "<enclosing type>".  In C, the nesting is ignored and
                <type> and its enumerator constants can be accessed
                as if they were not nested.  <However, the type and
                its enumerators are members in C++>.  <Fix>.

 Description    C allows types to be declared within other types.
                For example:  struct S { int a; enum E { first,
                second, third} b; int c; }; In C++ the enum E would
                not be accessible without using the ::  operator.

 User Action    Declare the nested type before declaring the
                enclosing type.
