Oh, I had even less work in mind. If the test makes non-portable assumptions
about alignment, just tag it as unportable due to alignment, and then for sparc
and sh, just set that flag. As others find other testcases for other machines
that suffer the same general problem, they eventually would find and switch to
the more maintainable form. As someone did a new port, and saw the testcase
fail, they would glance at it, see the non-portable due to alignment, say,
yeah, that applies to me a well, and then just add their port to the list.
Once they did this, then presto, all the testcases would suddenly turn off,
which is what they want to happen.
