--------------------
01g,29jan93,pme  made smMemAddToPool() return STATUS.
01f,15oct92,rrr  silenced warnings
01e,29sep92,pme  changed user callable routine names 
                 moved smMemPartShow prototype to private/smMemPartLibP.h
01d,22sep92,rrr  added support for c++
01c,28jul92,pme  made smMemPartCreate return PART_ID instead of SM_PART_ID.
01b,28jul92,pme  removed unnecessary includes.
