Hi there,

I=92m using g++ for the first time via gcc 4.1.2.
I=92ve written a little code (first C++ oriented and because guys with whic=
h I
work come from C, it is slightly modified to compile with G++ and gcc)

>>>>>>>>>>>>>>>>>>> Code >>>>>>>>>>>>>>>>>>>>>>>>>>>>
=A0
//#include <iostream>
#include <stdio.h>

//using namespace std;

int main()

{

=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 int toto;

=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 short tata;

=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 toto =3D 1111118;

=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 tata =3D toto;=A0 //error 1!

=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 //cout << toto << "tata:" << =
tata << endl;

=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 printf("%d %i",toto,tata);

=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 //return 0; //error 2 because=
 no return

}

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

I i compile with gcc (cc), it detects no int returned error (OK good point)
But the downcast (tata =3D toto) doesn=92t raise any warning!

If I use G++ the downcast is not detected and even more the return is not
also detected (!)

I was thining that Gcc was really strict and I choose it because I was
thinking that, I=92m quite disappointed :/
I=92ve tried =96Wall =96Wextra =96pedantic + a ton of other switch with no =
luck=85

Do i miss something=A0?=20

How can I put Gcc in =93user is stupid I need to check all=94 mode?
