23<P>Declaration disabling use of expanded arena in main memory.</P>
24<P>The main memory expanded arena can never be used when there is no expanded main memory. This applies to operations on the DS.</P>
25<P>If you are going to call this function, do so before calling <a href="OS_InitArena.html"><code>OS_InitArena</code></a> or <a href="../init/OS_Init.html"><code>OS_Init</code></a>.( <code>OS_InitArena</code> is called from <code>OS_Init</code>.)</P>
26<P>To maintain compatibility with previous versions, there is also a way to specify <nobr><code>NITRO_MEMSIZE=4M</code></nobr> when compiling the OS library.</P>
