commit 7288ffe050337c7c2389f0270f671b98673dc350
Author: Junchao Zhang <jczhang at mcs.anl.gov>
Date:   Tue Oct 29 11:15:19 2013 -0500

    Fix a problem in passing thread id to a function
    
    The old code used (void*)(intptr_t)i to pass the thread id i.
    However intptr_t is C99, so I changed it to (void*)(long)i.
    
    Direct usage of (void*)i will issue a compilation warning
    saying it is dangerous to convert integer to pointer.
    
    Fixes #1956
