Comment(by nalaurethsulfate):
while it might be easier to fix the cabal program also handles the same
test case incorrectly:

I don't think that this is terribly surprising though, and shouldn't be to
difficult to fix. If someone could please explain why CPP lines wouldn't
be in code blocks (no matter how they are delimited) that would help a
lot.
