You might be reading more into that statement than I meant.
You have to supply Pyrex/Cython versions of the C declarations,
either hand-written or generated by a tool. But you write them
based on the advertised C API -- you don't have to manually
expand macros, work out the low-level layout of structs, or
anything like that (as you often have to do when using ctypes).
