C99 6.10.1 #4:

  [...] After all replacements due to macro expansion and the defined
  unary operator have been performed, all remaining identifiers
  (including those lexically identical to keywords) are replaced with
  the pp-number 0, and then each preprocessing token is converted into
  a token. The resulting tokens compose the controlling constant
  expression which is evaluated according to the rules of 6.6. [...]
