EGCS does not complain about this, even though it is wrong. 
However, it does complain about

	int main()
	{
		if (int i = 10)
			i++;
		++i;
	}

Something funny happens about scoping around the if.  While
this probably isn't a bug (since it doesn't generate incorrect
code since the i++ doesn't do anything) it certainly is a quirk.
