Oh, so we are supposed to support this, so it does become important to
fix this for 24.3.

I'd still like to know if the naive approach of just taking the original
24.2.93 tarfile and adding to src/unexaix.c

  #define ADDR_CORRECT(x) ((int)(x))

happens to work...?
This may be nonsense, but should be quick to check.
