Oops.  At times I tend to scan bug reports a bit less thorough than
I should.

A side note to the above: Please instead use (and teach your users to
use)
  ./configure LIBS=-lz

because that way, config.status can remember that you set this manually.
In case a configure recheck is triggered from your build system, that
setting will be retained then, and also `./config.status --version'
will tell you about it (which is a nice help for people that tend to
forget quickly).

No, I've never heard of a problem with that.
