No, it would be bad, because on most other platforms this behavior
is probably a bug, and altering the tests like that would mask the bug.
The unconditional-acceptance thing has to be used with great caution;
preferably only for issues that we expect on many platforms (such as
locale dependencies).
I have noticed an increasing tendency among the buildfarm crew to think
that the regression tests should show zero diffs on all platforms no
matter what. That is not the design goal. The intent is to tell you
about possible problems. If you decide that a particular diff isn't
really a problem, fine, but that doesn't mean we should mask the same
symptom everywhere.
