gcc and g++ (all the versions I've ever used) don't give unused variable
warnings in a lot of cases where there are unused variables. Simple sample
code:
int test1 ()
{
int x = 3;
return (2);
}
int test2 ()
{
int x;
x = 3;
return (2);
}
They only give an unused variable warning in test1 function. They should warn
in both cases.
