+ * Revision 1.90 2002/04/02 14:57:28 oes
+ * Made sending wafers independent of FEATURE_COOKIE_JAR
+ *
+ * Revision 1.89 2002/03/31 17:18:59 jongfoster
+ * Win32 only: Enabling STRICT to fix a VC++ compile warning.
+ *
+ * Revision 1.88 2002/03/27 14:32:43 david__schmidt
+ * More compiler warning message maintenance
+ *
+ * Revision 1.87 2002/03/26 22:29:54 swa
+ * we have a new homepage!
+ *
+ * Revision 1.86 2002/03/25 17:04:55 david__schmidt
+ * Workaround for closing the jarfile before load_config() comes around again
+ *
+ * Revision 1.85 2002/03/24 15:23:33 jongfoster
+ * Name changes
+ *
+ * Revision 1.84 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.83 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.82 2002/03/13 00:27:05 jongfoster
+ * Killing warnings
+ *
+ * Revision 1.81 2002/03/12 01:42:50 oes
+ * Introduced modular filters
+ *
+ * Revision 1.80 2002/03/11 22:07:05 david__schmidt
+ * OS/2 port maintenance:
+ * - Fixed EMX build - it had decayed a little
+ * - Fixed inexplicable crash during FD_ZERO - must be due to a bad macro.
+ * substituted a memset for now.
+ *
* Revision 1.79 2002/03/09 20:03:52 jongfoster
