With the following input:

typedef struct foo
{
   unsigned char m;
   unsigned char n;
} foo;

typedef struct Foo
{
   unsigned char m;
   unsigned char n;
} bar;

typedef Foo moo ;


and this AST visitor fragment:

   bool VisitTypedefDecl( TypedefDecl * dtDecl )
   {
      const QualType &  qtUnderLying         = dtDecl->getUnderlyingType() ;
      const Type *      tUnderlying          = qtUnderLying.getTypePtr() ;
      string            theUnderlyingType    = qtUnderLying.getAsString( ) ;
      string            typeDefinitionName   = dtDecl->getName().str() ;
      string *          pName                = NULL ;
      bool              ignore               = false ;

      if ( const RecordType * r = dyn_cast<RecordType>( tUnderlying ) )
      {
cout << "RecordType: " << typeDefinitionName << ","<< theUnderlyingType <<
":" << r->getDecl()->getName().str() << endl ;


That RecordType cast is only successful for the moo typedef, giving:

RecordType: moo,struct Foo:Foo

What sort of type would tUnderLying be for the bar and foo typedefs?
