To cite landley on this ".. every C compiler since DOS times does
DeadCodeElimination".
While i personally see no great benefit in moving the duty of the
preprocessor into the C compiler domain and to rely on eventual passes
being performed, the current maintainer did choose to go that route.
Perhaps complain to him that your compiler has "missed optimization"
bugs ;)
