choroba:
Actually, you *do* need a stack if you're going to properly handle the #else clauses. Otherwise, you won't remember the previous value(s) of the print vs. don't print states.
#if 0
this shouldn't print
#if 1
nor should this
#else
nor this
#end
#else
but this should
#if 1
as should this
#else
but not this
#end
This should print, but where are you storing the information
to know it without a stack?
#else
If you got that one right, howzabout this one?
#end
