NESTEDTYPE

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.
