Message        The type "<type>" is declared nested within
                "<enclosing type>".  In C, the nesting is ignored and
                <type> can be accessed as if it were not nested.
                <However, the type is a member in C++>.  <Fix>.

 Description    C allows types to be declared within other types.
                For example:  struct S { int x; struct S1 { int a;
                int b; } y; }; In C++ the struct S1 would not be
                accessible without using the ::  operator.

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