Assigning a function with prototype
   void func (unsigned long arg);
to a function pointer with prototype
   void (*ptr) (unsigned arg);

(even on platforms where "unsigned long" is the same size as
"unsigned").

My comment was just for consistency with the rest of the code base.
I though we were not using plain "unsigned" anywhere else.  However,
after checking the code base, it seems there's already a number of
places that do so.  I don't really mind then, so I withdraw the 
suggestion to use "unsigned int".
