NESTEDENUM

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.
