commit 7b8bd055dfdeb7a0d9c264e088376ff8fa9341b1
Author: William Throwe <wtt6 at cornell.edu>
Date:   Mon Sep 14 19:09:51 2015 -0400

    ROMIO configure looks for lstat in wrong header
    
    The ROMIO configure script checks for a declaration of lstat in
    unistd.h, but, at least on the Linux machines I checked, lstat is in
    sys/stat.h.  (The detection failure led to a linker error when building
    ROMIO as part of OpenMPI on one of my admittedly strangely configured
    machines, somehow.)  It appears from the man page that either location
    is possible, so check both.
