The commented out flags won't break anything, those are specifically in the newly added test compile options section. Those flags weren't being added at all before. The tests should still be passing (unless I've really screwed up)

I wanted to land this patch quickly since it should hopefully unblock @lntue 's own cmake rewrite. Hopefully it won't cause too many issues for your patch (which I'm in the middle of reviewing, I will hopefully be done soon), I tried to keep this change as small as reasonable.
