I had messed up the handling of declarators for combinations of pointer,
function, and array: the pointer would get lost (and presumably arrays
of functions etc). I think I had gotten confused and thought things were
a tree rather than a simple list, but Holub set me straight once again
(I've never regretted getting that book). Once I understood that, it was
just a matter of finding all the places that needed to be fixed. Nicely,
most of the duplicated code has been refactored and should be easier to
debug in the future.
