  27. Given that #error generally _does_ cause processing to halt, it could
  28. simply be:
  29.  
  30. "Causes the implementation to produce a diagnostic message that inlcudes
  31. the specified sequence of preprocessing tokens, but processing of the
  32. translation unit continues."
  33.  
  34. I.e. whether processing halts or not isn't defined with #error, but with
  35. #warning, processing is explicitly defined to continue.
