[mvapich-discuss] Issue compiling recent osu benchmark

[Jonathan Perkins]

Thank you for the report.  We'll provide a check for MPI-3 support in
the next release of the OSU Micro-Benchmarks.  In the meantime you can
follow Jeff's suggestion to use the -k option of make so that the
other benchmarks will build successfully.
