Right. It's meant to prepare a potential switch of the way pointers are
declared, as well as making it less likely to get the declarations wrong. C
is suprisingly relaxed about these things, but Cython shouldn't be.
I guess the message could be improved, though. Maybe add something like
"mix of pointers and values" as a hinting example.

I added an entry. Could you provide a code snippet that shows what you were
doing? Just to be sure it's really a problem in your code and not a wrong
assumption in Cython. Optimisations shouldn't break code.
