Frankly, I don't know.  However, these message are indeed mere warnings;
the log as well as the file system shows correct filenames after
extracting.  Furthermore, the messages 'continuing with "central"
filename version' don't make sense to me, since the filenames in the
local file headers are identical to those in the central directory headers.

Anyhow, since everything appears to work with unzip 6.0.0 and there are
better tools anyway, I don't think this issue deserves spending much
time. :)
