Sorry - The copy constructor is not being called

[ssacek]

The program below works for the Solaris and Microsoft compilers, but not for
the GCC compiler. Can anybody else verify this, and or if it's already been
fixed?  
 
I'm using:
-bash-3.00$ gcc -v

      S( const S & ) {  printf( "Inside copy constructor \n" );  }
};
 
S  f( void )

      S s1;
      return s1; 
}
 
int main ( int, char ** )

      S  s1;
      S  s2( s1 );  // must call the copy constructor
      S  s3 = f();  // must call the copy constructor
      S  s4( f() ); // must call the copy constructor
      return 0;
}
 
#if 0
      //  GCC output is:
