You are lucky, lots of replies to your post.
I asked why the first example did not compile and did not get a reply. 
At least K.A.R.L. got it to work.  I'd be interested in any comments.
     Regards Ian
#include <stdio.h>
// --- class TObject1 definition
class TObject1
{ public:
    TObject1();
    virtual void foo();
};
TObject1::TObject1()
{ foo();
}
void TObject1::foo()
{ printf("TObject1::foo\n");
}
// --- class TObject2 definition
class TObject2 : public TObject1
{ public:
    TObject2();
    virtual void foo();
}
TObject2::TObject2()   : TObject1()
{ }  

//************* ERROR return type spec for constructor invalid.

void TObject2::foo()
{ printf("TObject2::foo\n");
}
void main(void)
{ TObject1 *O1;  

//*******Warning return type for main changed to integer type.

  TObject2 *O2;
  printf("TObject1 creation : ");
  O1=new
  TObject1();
  printf("TObject2 creation : ");
  O2=new TObject2();
  //
  delete O2;
  delete O1;
}
