<p dir="auto">While <code>size_t</code> is C standard, <code>ssize_t</code> is not. If it is not available, we should <em>not</em> typedef it to an <code>int</code>. E.g. on Win64, <code>int</code> is 32 bits and <code>size_t</code> is 64bits.</p>
<p dir="auto">IMO, we better leave it to the application programmer, to do the right thing. E.g. on Windows this could be</p>
