Hmmm, this should have been excluded via HAVE_LOG2 definition ...

but this worked.

I needed to turn the other definitions in src/hhalign/util-C.h into
comments since the ifndefs did not worked even after including config.h.

Its not as nice as I would like it to be but builds now and is uploaded.

Thanks for the hints
