Since the patch was actually written by Bernd Schmidt I do think that
it is safe and so I have checked it in to the branch. Momchil only
mentions half of Bernd's patch but I have taken the liberty of
applying the other half as well (affecting gcc/config/arm/arm.c). No
regressions were exposed by applying this patch.
Cheers
