Function notcurses_version_components 

pub unsafe extern "C" fn notcurses_version_components(
    major: *mut c_int,
    minor: *mut c_int,
    patch: *mut c_int,
    tweak: *mut c_int,
)

Cannot be inline, as we want to get the versions of the actual Notcurses library we loaded, not what we compile against.
