Comment (by mascguy):

 Looks good so far: The latest snapshot fixed the test compilation errors,
 and the "light" (auxiliary) test suite passes. One test is skipped though,
 is that normal/expected (at least with an older compiler like gcc-4.2)?

 As for the in-depth test cases, I'm still waiting for those to finish. But
 most appear to be passing, with some (hopefully expected?) failures. I'll
 provide the full test suite log once it finishes.
