  When compiling original QuakeWorld QC there are instances where
  code overwrites constants. This is considered an error, however
  for QuakeWorld to compile it needs to be treated as a warning

  .It Fl W Ns Cm directive-inmacro
  Warn about the use of preprocessor directives inside macros.
 +.It Fl W Ns Cm builtins
 +When using a function that is not explicitly defined, the compiler
 +will search its intrinsics table for something that matches that

 +be unexpected, so enabling this will produce a diagnostic when
 +such a function is resolved to a builtin.
