  * Revisions   :
  *    $Log: errlog.c,v $
+ *    Revision 1.65  2008/01/31 14:44:33  fabiankeil
+ *    Use (a != b) instead of !(a == b) so the sanity check looks less insane.
+ *
+ *    Revision 1.64  2008/01/21 18:56:46  david__schmidt
+ *    Swap #def from negative to positive, re-joined it so it didn't
+ *    span an assertion (compilation failure on OS/2)
+ *
+ *    Revision 1.63  2007/12/15 19:49:32  fabiankeil
+ *    Stop overloading logfile to control the mingw32 log window as well.
+ *    It's no longer necessary now that we disable all debug lines by default
+ *    and at least one user perceived it as a regression (added in 1.55).
+ *
+ *    Revision 1.62  2007/11/30 15:33:46  fabiankeil
+ *    Unbreak LOG_LEVEL_FATAL. It wasn't fatal with logging disabled
+ *    and on mingw32 fatal log messages didn't end up in the log file.
+ *
+ *    Revision 1.61  2007/11/04 19:03:01  fabiankeil
+ *    Fix another deadlock Hal spotted and that mysteriously didn't affect FreeBSD.
+ *
+ *    Revision 1.60  2007/11/03 19:03:31  fabiankeil
+ *    - Prevent the Windows GUI from showing the version two times in a row.
+ *    - Stop using the imperative in the "(Re-)Open logfile" message.
+ *    - Ditch the "Switching to daemon mode" message as the detection
+ *      whether or not we're already in daemon mode doesn't actually work.
+ *
  *    Revision 1.59  2007/11/01 12:50:56  fabiankeil
  *    Here's looking at you, deadlock.
