I've compared a sample of European time zone files in 
kdepim-3.5.5+/libkcal/libical/zoneinfo with the pre-Hasso files. Apart from 
the removal of an LMT entry starting at year 0001, which I don't think we 
need to worry about, they seem to be basically the same. There are a few 
small differences, many of which are for years in the 1940s, which I suppose 
are probably corrections to fix erroneous data. For the most part recent 
years seem to agree between the two versions. I think it's safe to assume 
that there is no fundamental problem with the new files, and hopefully they 
have a number of fixes in them. So I would be in favour of committing your 
new files into 3.5 branch.

FWIW, the format (i.e. lists of RDATEs) is the same as the old version I 
looked at.
