Pb on gcc : no warning on information lost.

[Yves Mocquard]

Hello !
I am French, sorry for my bad english.

When I use gcc or g++ , I like when the compilator detects bug, with a 
an error of compliation or a warning.

see this code :

long long fct()
{
    return 0x123456789;
}
int main()
{
    int a = fct();
    cerr << a << endl;
}

when I compil with : g++ -Wall fic.cpp
I think that there should be a warning.
And there is nothing, the bug is not detected.

I think that it not normal.

Regards,
