The patch

Hello.
I have a patch which adds an option to suppress warnings about operators'
precedence. For example for this code

bool a, b, c;

// Something...

if(a && b || c)
{
  // Do something...
}

g++ will print the "Suggest parenthesis around a && b" warning. But the &&
operator has a higher priority, so parenthesis here needed to ensure that all
is OK.
