Eugene Sandulenko 64043ff1fc Removed some not necessary #defines which could (and did) lead to program 
logic misinterpretation. I assume these were added for readability, but
 (a) names suggestet that they're class variables but they didn't
 (b) their use wasn't consistent, i.e. there were places where variables were
     used directly, not by means of the macros
 (c) they didn't save that much space because they are used in few places.
