I ran into this before. The way I got around it is...

#if(Z>0) #if(array[X][Y][Z-1]>0) do_something.. #end #end

I think it is the negative element of the array is accessed during evaluation
that causes the error.
#ifndef with an array with a negative element or a positive element out of range
will cause an error too. Even throuh clearly element [-1] doesn't exist.

Have Fun!
