Perhaps we are discussing different kinds of variables. Your macro tests 
if a given preprocessor symbol is defined or not. Such a symbol must be 
defined (or not) when the preprocessor runs. Probably the closest analog 
in Ruby is a global constant. I was talking about variables such as 
automatics or statics, much closer to Ruby's variables.
