cleanliness in the main library (diffs to be sent to the vendor as in
the past).
The installed library is now called libWN, as vendor's build would call
it, rather than libwn2, as the previous version of the port called it.
This may upset the client port of p5 -- the maintainer is notified and
awaits this commit.
