This means that you are passing 'ctypes function' objects around, in
variables.  The only thing you can do with ctypes functions is call them
directly.  For now you have to find a workaround, e.g. pass stub RPython
functions around.  E.g. instead of:

    f1 = mylib.f1
    f2 = mylib.f2

    def invoke(f):
        return f(17)     # 'f' holds a variable ctypes function object



    f1 = mylib.f1
    f2 = mylib.f2

    def f1stub(x): return f1(x)
    def f2stub(x): return f2(x)

    def invoke(f):
        return f(17)     # 'f' holds a regular RPython function


(Note: this and a number of other ext-compiler or rctypes limitations
could be removed with a bit of work; don't hesitate to tell us if a
particular workaround seems really awkard in your cases.  I'd love this
kind of input, to know where to put efforts for more support.)

A bientot,
