  * Revisions   :
  *    $Log: errlog.c,v $
+ *    Revision 1.71  2008/06/28 17:17:15  fabiankeil
+ *    Remove another stray semicolon.
+ *
+ *    Revision 1.70  2008/06/28 17:10:29  fabiankeil
+ *    Remove stray semicolon in get_log_timestamp().
+ *    Reported by Jochen Voss in #2005221.
+ *
+ *    Revision 1.69  2008/05/30 15:55:25  fabiankeil
+ *    Declare variable "debug" static and complain about its name.
+ *
+ *    Revision 1.68  2008/04/27 16:50:46  fabiankeil
+ *    Remove an incorrect assertion. The value of debug may change if
+ *    the configuration is reloaded in another thread. While we could
+ *    cache the initial value, the assertion doesn't seem worth it.
+ *
+ *    Revision 1.67  2008/03/27 18:27:23  fabiankeil
+ *    Remove kill-popups action.
+ *
+ *    Revision 1.66  2008/01/31 15:38:14  fabiankeil
+ *    - Make the logfp assertion more strict. As of 1.63, the "||" could
+ *      have been an "&&", which means we can use two separate assertions
+ *      and skip on of them on Windows.
+ *    - Break a long commit message line in two.
+ *
+ *    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.
