I thought of that, but I hadn't suggested this idea because it seemed so weird. Promoting to int would not be odd, but promoting to long is weird. Anyhow, you're right; that's another option, and, despite weirdness, plausible. I can't think of a way in which it changes current behavior, unless you call __builtin_expect with a long long, and that's probably not going to do what you expect right now anyhow. -- Mark Mitchell CodeSourcery [EMAIL PROTECTED] (650) 331-3385 x713
