Is ExamDiff some well known Windows program? Does it accept command

program or script to convert the GNU style arguments to a form
acceptable to ExamDiff.

The external diff program exited with a return value of 2. Subversion
expects the program to return 0 or 1. You may have to use the wrapper
program or script to convert the ExamDiff return value.

I don't know what an ExamDiff return value of 2 means but I'd guess it
indicates that the program failed, possibly because it doesn't
understand GNU diff style command line arguments.
