   I will take a look at it. I have looked at Matts BICOM where its very
easy to replace the compressor with any other compressor bijective or not.
I like the elegance with which it was added in his code. But it will be
sometime. On my last PC I had made extensive changes to bzip2 it had a
lot of places that could be cleaned up to save a few more bytes.

   I will try to follow your code and see if it complies under DJGPP if it
does I may replace the compressor with a simple bijective compressor just
to see if it can be done. However I think I can only send you the changes
not the full package since not really sure if Americans can legally write
crypto any more. You have the advantage sir of living in a more free
country in this regards.
