<p>SQLite [version 3.8.4.1] is a patch against [version 3.8.4] that fixes
   two minor issues:
<ol>
<li> Work around a C-preprocessor macro conflict that causes compilation
     problems for some configurations of Visual Studio.
<li> Adjust the cost computation for the [skip-scan optimization] for
     improved performance.
</ol>
Both of these issues came to light within minutes of tagging the previous
release.  Neither issue is serious but they can be annoying.  Hence, the
decision was made to do a quick patch release to address both issues.
