<h3 class="section">16.1 Available Symbols</h3>
<p>When GCL is built, those symbols in the system libraries which
are referenced by functions linked in in the list of objects
given in <samp><span class="file">unixport/makefile</span></samp>, become available for reference
by GCL code.
<p>On some systems it is possible with <code>faslink</code> to load <samp><span class="file">.o</span></samp> files
which reference other libraries, but in general this practice is not
portable.
