TRACE - Debugging helper macro to trace messages. Allegro game programming library.

       Debugging  helper  macro.  Normally  compiles away to nothing, but if you defined the preprocessor symbol
       DEBUGMODE before including Allegro headers, it passes the supplied  message  given  in  ASCII  format  to
       al_trace().  Example:

          #define DEBUGMODE
          #include
          ...
          void my_blitter(BITMAP *source, int flags)
          {
             static int count_call = 0;
             TRACE("my_blitter() called %d times.\n", count_call++);
             ...
          }
