case constant 'constant' too big for the type of the switch expression
The specified constant in a switch expression was too large to fit in the type to which it was assigned. The following example causes this warning:
void main()
{
int i; // maximum size of unsigned long int is 4294967295
switch( i )
{
case 4294967295: // OK
break;
case 4294967296: // warning
break;
}
}
