Yes, that was the nonsence interpretation. :-) > You could use "i=++i" which would increment i, then save the r- value > and assign to the l-value, but then again, i++ would be much simplier, > no? Right. But there may be other style mishaps in Vadim's code that gcc 3.4 doesn't like. We just don't know.
