No space overhead if you deal with unconstrained arrays?
I use gmp-2 (the GNU bignum package). Perhaps I'll never look at the
contents of the memory regions form Ada. I need no safely typed Ada
structure.
Does GNAT's allocate call malloc? That would be an additional overhead
of one word (that depends on the malloc, of course) for malloc's header.
