    CREATED    ********   11/22/94
	SKAYOOR		MODIFIED    08/19/02
				Bug 2445796: Added a new member m_origname to OFIELD Class.
    SKAYOOR		MODIFIED	03/08/02
				Bug 1361495: Created a member in ODynaset to 
				hold the fieldname. This fieldname will freed 
				next when ODynaset::GetFieldName is called or 
				when ODynaset object is freed.
    RWOOLARD	MODIFIED	03/20/95
    			bug#	262914	*ErrorText should return const char *
    					262723	Added overloaded OParameter.Add(..., OValue)	
    PCHARI      MODIFIED        03/19/98
				bug#    624443  *NT 3.5.1 does not support CoInitializeEx
				and so this fix to explicitly link with ole32.dll
	MLAKSHMI	MODIFIED        01/06/99
				changed the OTYPE_ROWID value to 104 from 11
	PCHARI		MODIFIED	06/03/99
    			bug#	806756	Added critical section object
