Do not believe everything you read from apple developers, this statement is
completely wrong.

Short-circuit evaluation works with the preprocessor, you can check with
this for example:

#if defined(x) && x    

What does not work is a malformed expression:

#if defined(x) && x(42)

... because x(42), if x is not defined, expands to 0(42), which is not
syntactically valid as an expression.
