--------------------
01g,05may02,mas  added volatile pointers (SPR 68334)
01f,01aug94,dvs  backed out pme's changes for reserved fields in main data structures.
01e,20mar94,pme  added reserved fields in main data structures to allow
		 compatibility between future versions.
01d,29jan93,pme  added little endian support
01c,29sep92,pme  changed objId field to value in SM_OBJ_NAME 
		 and SM_OBJ_NAME_INFO
01b,22sep92,rrr  added support for c++
