Re: libc/printf bug

Both, though. The original post hadn't included stdio.h, so all
arguments would be pushed on the stack(typically) as ints. With a
prototype for printf, which accepts varadic arguments, the promotion
rules are different, floats become doubles, char/short become ints and
similar.

The promotion rules are actually the same. But see my other post.
