That ticket only talks about NullXX being replaced with NULL, which 
seems to fix only part of the problem. There are also SVt_RV, 
PL_no_symref and OP_SETSTATE missing.

I tried replacing SVt_RV with SVt_IV, but the tests failed under 
5.10.1. Perhaps I misunderstood perl5120delta.

No idea what to replace the other two with.
