ndk-r7 can not identify the va_list type
<p>I have set up the ndk-r7 compiling environment in Eclipse and compile the C code for .so library file. Then the va_lsit type of C code can not be identified and be compiled.</p>

<p>It is no problem when I compile sample code of ndk. But it did not use va_list type in sample. It has stdarg.h. And it has the va_list definition in some stdarg.h of ndk catalogue.</p>

<p>The error like this:</p>

<pre><code>jni/CommAbstractLayer.c: In function 'SetCommunicationLineVoltage':
jni/CommAbstractLayer.c:1414: error: invalid initializer（this line points the following line: va_list   args = NULL;）
</code></pre>

<p>The code like this:</p>

<pre><code>#include &lt;stdarg.h&gt;
......
W_INT2 SetCommunicationLineVoltage(BYTE ucChangeTimes, ...)
{
va_list args = NULL;
......
return 0;
}
</code></pre>
