* Some math functions become intrinsic in release mode, so we need to convert all the math functions into SDL math functions, like we did with the stdlib functions. * Constant initializers of 8-bit values become calls to memset() in release mode, but memset() itself is an intrinsic when explicitly called. So we'll just explicitly call memset() in those cases.
