+ <listitem>
+ <para>Certain options, such as <option>-O</option>, turn on
+ via-C compilation, instead of using the native code generator.
+ Include files named by <option>-#include</option> options
+ or in <literal>foreign import</literal> declarations are only
+ used in via-C compilation mode. See <xref
