Even z88dk does this? I'm surprised. It would inherently slow down the fastest code if all variables were expanded into something like long type before being dropped back to a byte form. This is particularly crucial on such a small machine as the spectrum - you'd be costing bytes AND time. I think forcing it wish CAST is a reasonable option, generally.
At the very least, let's keep this behaviour command line optional, if the compiler changes - I'd expect smaller, faster code that works fine for most cases to come out of it.
