test-all - rename duplicate classes for consistent test count
test-all reports varying test counts from build to build. This seems to be due to duplicate class names in the test suite.
I pushed PR 1763 to the git repo with several renamed classes.
I've been using the patch in ruby-loco MinGW builds. The test summary page Ruby MinGW Test Results has shown consistent results.
In addition to PR, patch attached. Thanks, Greg
