modification history
--------------------
01g,01aug94,dvs  backed out pme's changes for reserved fields in main data structures.
01f,20mar94,pme  added reserved fields in main data structures to allow
		 compatibility between future versions.
01e,29jan93,pme  added little endian support
01d,22sep92,rrr  added support for c++
01c,23aug92,jcf  fixed struct reference.
01b,30jul92,pme  added smObjTaskDeleteFailRtn declaration.
01a,19jul92,pme  extracted from smObjLib v1d.
