Looking for a light-weight cross-platform C threading library : <p>I wanted to use OpenMP for this, but it is not appropriate for my purposes: creating my own thread pool.</p>

<p>So, this needs to be C89 code with, of course, platform specific code for windows and unices.</p>

<p>I need this for a C only library, so no C++, boost C++11, etc.</p>

<p>Thanks!</p>
