The main.c part of the patch strikes me as irrelevant to the claimed
purpose and unlikely to accomplish anything except breaking things.
Do you have a system the main.c "__alpha" code is relevant to, on which
to test that you did not break it?

Other than that, it looks like basically a good idea.  But...

This seems like living dangerously.  You do realize that this patch will
invalidate our trust that the code works on every single supported
platform?  I think beta3 may be a bit late in the game for this sort of
thing, because we've already gotten a good bit of the testing we can
expect to get for lesser-used platforms during this beta cycle.

At the very least I'd like to see the decision discussed on -hackers
and not buried in -patches.
