Replying to jimmy:

changed bignum.pmc to use GET_ATTR syntax

As noted in  this comment on TT #1348, I've been looking at whether your patches work with one another, "work" meaning "does not prevent Parrot from completing make successfully".

This patch works with:

* the Vtable.pm patch submitted in TT #1354

* the arrayiterator.pmc patch submitted in TT #1349

* the bigint.pmc patch submitted in TT #1350

Have not yet run make test.

This patch looks sane and causes no test failures. I've committed it as r42971. Thanks!
