Also minor comment changes to internal.h and external.h.
+Wed Oct 27 11:45:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
+
+ * common.h (NLM_SIGNATURE): Do not define (it's different for each

+
+Tue Aug 31 13:24:15 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

+
+Sat Jul 31 02:12:14 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
+
+ * common.h (NLM_HIBIT, NLM_HEADER_VERSION): Define.

Mon Jul 19 22:12:40 1993 Fred Fish (fnf@deneb.cygnus.com)
* (common.h, external.h, internal.h): New files for NLM/NetWare
(3) A auxiliary header that has various optional fields in no specific
order. There is no way to identify the end of the auxiliary headers
except by finding a header without a recognized 'stamp'.
