I don't see the problem...
Just use a pointer to a pointer to a pointer to a ...
Every array in C is just a hidden pointer and if you try to dynamically allocate an array in C then you are left only with one option: malloc, calloc, realloc

I'm having a devil of a time trying to figure out what seems to be a
pretty basic scenario: declaring a multidimensional array in the
interface section of a class when the array dimensions are unknown
until runtime. Can anyone point me in the right direction with this one?

If you mean C arrays, AFAIK you can't. C99 spec'ed variable length arrays
(VLAs) don't work that way. It will work out, IIRC, that you can only use
them as stack variables. And not static ones either. I believe it's because
of the initialization rule for VLAs.
