/*
 * $Revision: 1.12 $
 *
 * 05 Apr 02 - Mike: Created
 * 14 Jun 02 - Mike: Added windows test for calc.exe
 * 20 Jun 02 - Mike: Added test for microX86Dis
 * 08 Jul 02 - Mike: Test more exe file formats
 * 30 Sep 02 - Trent: split microDis tests
 * 30 Sep 02 - Trent: remove dependancy between microDis test1 and Elf loader
 * 05 Aug 05 - Mike: added borland test; check address of main (not just != NO_ADDRESS)
