The CODE: section defines RETVAL but does not implicitly return RETVAL according to the perlxs manpage. Effectively, an undefined single value is being returned from all of your functions.

To solve this, model the functions according to the following form:

I32
ds_scopestack_ix()
    CODE:
        RETVAL = PL_scopestack_ix;
    OUTPUT:
        RETVAL

Good luck!
