	Change History (most recent first):

		 <2>	  2/7/01	JL		[2500429]  Changed null output parameters to real variables when
									calling GetSharedLibrary to prevent crashes with older versions
									of CFM. Added standard header. Updated names of includes. Added
									C function implementations of accessors that used to be macros
									since the generated Pascal headers no longer contain
									implementations. Updated various other routines to use new
									calling convention of the accessor functions.
