Very good; give the man a bannana.   Gzip linked (shared) under 3.0 is 
actually about 100k, as noted in the log message.

Note also that if you are in a space-restricted environment but already 
have libz present (think 'ppp router floppy') you win again.  I felt 
the minor build/space bloat (a few tens of k and a few seconds) was a 
reasonable tradeoff.  Saving 80+k on a potential install floppy isn't a 
bad win either.

Then, if you are worried about the GPL, it's a win from a different 
direction.  But we've covered this already.
