Could you give a quick explanation why?  I thought the whole point of
the "extern" specifier was to flag that this variable was defined
elsewhere.  Otherwise, doesn't it imply that the API pointer is
defined in each file that includes arrayobject.h?

i.e. shouldn't headers declare "extern double x" for everything except
the file that actually defines x?

I should go back and read my copy of K&R...
