[vorbis-dev] BCB build successful?

[OmegaDan]

Some Results :

At this point I have to ask -- are you absoultley sure these are the same
exact sources doing this ?  I wonder if they have different codebooks? 
That could be tested with the rehuff util Segher Boessenkool wrote --
theoretically when optimized they would be identical if the codebooks were
different?.
