$Log: LateImportTest.c,v $

Revision 1.5  2002/11/08 23:11:27         

Convert nil to NULL. Convert MoreAssertQ to assert.

Revision 1.4  2001/11/07 15:50:12         

Tidy up headers, add CVS logs, update copyright.

         <3>     19/9/01    Quinn   Take advantage of new, simpler API. No more dummy CFM exports!

         <2>    18/10/99    Quinn   Expanded tests to cover some extra cases.

         <1>     15/6/99    Quinn   First checked in.
