No, they are both equally bad. "30" sounds sharper, but the problem is the
stuttering and breaking. The problem is equally prevalent in both. Any

I wanted a standalone binary, and that is why I built with --enable-static,
and didn't want it to depend on external library based from here:

configure options help solve the problem?
Thanks again for your help.
