  Log:
  Rework the directive parsing code. Instead of using a lot of strcmp()s
  on every line that starts with a dot use a minimal perfect hash
  function and a single strcmp() on the first word after the dot
  to find out whether it is really a directive call and, if yes, which
  one. Then directly dispatch to a handler function for that directive
  (or fall through to the dependency handling code). This makes the
  directive parse a little bit more strict about the syntax: the directive
  word must be followed by a character that is not alphanumerical and not
  an underline (making .undefFOO illegal); .endif and .else can only be
  followed by comments.
