That is very good use of macros.. The way MSVC6.0 handles variable scope's in
for-loop's is a very frustrating bug, so if you absolutely have to use it, 
why not fix the
problem with the macro? I can't see how this macro could cause your code to 
break, unless
you are doing something like:

for (int i = 0;;)
{
}

int b = i;

in which case the fault is all yours..
