It looks to me more like the libraries are a mess, you have to use two different ones, and they don't have the same APIs even though the API was kind of meant to be speced?

But the argument is a bit besides the point - I gave two lines that I'm pretty sure (only checked one of the two cases for exact bytes count) do an equivalent check without an ifdef maze...
