I guess it's just personal preference. "for(;;)" looks really messy to me, and doesn't seem obvious that it signifies an infinite loop. I think that even the standard format for for loops (for (initialisation; condition; thing done at end of loop)) is quite unintuitive, and I have to think a bit to remember what each part does if one of them is omitted. It's also the only place I can think of where semicolons aren't expected at the end of a line (conventionally). I don't find a problem implicitly casting "1" to "true", I sort of do this automatically after programming in C for a while. Obviously if I were using java or something, I'd use "while(true)". Basically, I don't have to think much to know that it's an infinite loop :)
