Hi Helge,

I will have a look at merging my ARM implementation with this ASAP.
git-foo is probably the hardest part.

One thing I mentioned before, which doesn't seem to have changed in
this version, is your use of reinterpret_cast rather than const_cast in
cases like this:

  *reinterpret_cast<volatile T *>(&i)=v;

I suggested that this should be const_cast<volatile T&>(i)=v. Any
thoughts? (Anyone else?)

Cheers, Phil.
