Bug#548500: Help with slicer FTBFS on alpha - #548500

[Dominique Belhachemi]

I thought about it to exclude alpha. But this is not necessary anymore
because alpha isn't relevant for Squeeze.

On the other hand, changing the source code doesn't really work because
the AffineRegistration class is highly templatized. The .got subsegment
limit will probably be always exceeded.

Anyway, I will keep this bug open for now because it doesn't harm. Maybe
the alpha guys will remove this .got subsegment limit in the near
future.
