From: "Markus F.X.J. Oberhumer" Subject: SDL CVS patches below you will find some small patches against the current SDL CVS. It adresses these things: 1) Use "&" instead of "%" in some cases. For negative signed integers (x % 8) is not always (x & 7), and the compiler can produce slightly faster code when using "&" here. 2) Some const issues.
