  * $Log: log.c,v $
- * Revision 1.7  1995-06-19 12:40:18  quinn
+ * Revision 1.13  1997-09-01 08:54:13  adam
+ * New windows NT/95 port using MSV5.0. Made prefix query handling
+ * thread safe. The function options ignores empty arguments when met.
+ *
+ * Revision 1.12  1997/05/01 15:08:14  adam
+ * Added log_mask_str_x routine.
+ *
+ * Revision 1.11  1996/02/05 12:24:32  adam
+ * Implemented log_event_{start,end}-functions.
+ *
+ * Revision 1.10  1995/12/06  09:51:27  quinn
+ * Fixed the log-prefix buffer - it was too small and the setup code lacked
+ * a bounds-check.
+ *
+ * Revision 1.9  1995/09/29  17:12:34  quinn
+ * Smallish
+ *
+ * Revision 1.8  1995/09/27  15:03:02  quinn
+ * Modified function heads & prototypes.
+ *
+ * Revision 1.7  1995/06/19  12:40:18  quinn
  * Added log_file()
