I notice many unrelated whitespace changes in your patch, which makes
it harder to review. Attached is a rebased patch that removes all
whitespace at end of lines in a separate commit, and doesn't do such
whitespace changes in the rest of the commits.

You should use QEXPECT_FAIL instead of commenting out tests (unless
they don't compile, of course).

The code changes look good to me; although I'm not familiar with the
preprocessor code.
