If I read the Principles of Operation correctly, that's how long double values are stored. I couldn't find any obvious way, and the manual doesn't mention anything, either. (I recently had to look into a floating point issue, but it turned out that it was underlinking of libm, so that the compat double functions were called with long double arguments, so not much actual debugging needed.)
