Hello,

I hope this is the correct place to report a minor bug. If not, please point me in the right direction.

thanks for sending this patch. Since ROMIO happily provides its own lstat declaration and continues on its way, I never noticed this error. I committed this change to master: http://git.mpich.org/mpich.git/commit/7b8bd055dfdeb ==rob

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 I suggest checking both. Suggested patch below.

Thanks, William Throwe
