I must admit I did not dig this that much. OF_ADDRESS has !SPARC
dependency, so after removing COMPILE_TEST the issue should not happen
on SPARC. What about other platforms? They should behave I think the
same as before - fail if they were failing. Nothing gets worse which is
my main concern here.

If you have spare time, maybe you could investigate the compile testing
on other platforms as well and if something fails, fix it. But it seems
it is separate problem.

Best regards,
