    for further information about what that extension does.
<li>Enhance [FTS3] to avoid using excess stack space when there are a huge
    number of terms on the right-hand side of the MATCH operator.
<li>Added the [fts3tokenize virtual table] to the [full-text search] logic.
<li>Query planner enhancement: Use the transitive property of constraints
    to move constraints into the outer loops of a join whenever possible,
    thereby reducing the amount of work that needs to occur in inner loops.
<li>Enhance the [fts4aux] virtual table so that a TEMP fts4aux table can reference
    an [FTS4] table in main database.
<li>Discontinue the use of posix_fallocate() on unix, as it does not work on all
    filesystems.
<li>Bug fix:
    Only consider AS names from the result set as candidates for resolving
    identifiers in the WHERE clause if there are no other matches. In the 
    ORDER BY clause, AS names take priority over any column names.

<h2>Compiling A Loadable Extension</h2>

<p>Loadable extensions are C-code.  To compile them on unix-like operating

systems, the usual command is something like this:</p>

<blockquote><pre>
gcc -g -fPIC -shared YourCode.c -o YourCode.so
</pre></blockquote>

<p>Mac are unix-like, but they do not follow the usual shared library
conventions.  To compile a shared library on a Mac, use a command like
this:</p>

<blockquote><pre>
gcc -g -fPIC -dynamiclib YourCode.c -o YourCode.dylib
</pre></blockquote>
