- * Revision 1.13 1997-09-01 08:54:13 adam
+ * Revision 1.18 1998-10-28 10:27:00 adam
+ * New functions log_init_file, log_init_level, log_init_prefix.
+ *
+ * Revision 1.17 1997/12/09 16:11:02 adam
+ * Assume strerror is defined on Unixes as well. It's standard ANSI.
+ *
+ * Revision 1.16 1997/10/06 08:55:07 adam
+ * Changed log_init so that previous (if any) is closed.
+ *
+ * Revision 1.15 1997/09/29 07:13:13 adam
+ * Minor changes.
+ *
+ * Revision 1.14 1997/09/18 08:48:09 adam
+ * Fixed minor bug that caused log_init to ignore filename.
+ *
+ * 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.
