+modification history
+--------------------
+01e,29apr10,pad  Moved extern C statement after include statements.
+01d,01aug94,dvs  backed out pme's changes for reserved fields in main data structures.
+01c,20mar94,pme  added reserved fields in main data structures to allow
+		 compatibility between future versions.
+01b,22sep92,rrr  added support for c++
+01a,19jul92,pme  extracted from smFixBlkLib v1a.
