Subject: [OMPI devel] Fwd: 1.5rc5 has been posted
From: Larry Baker (baker_at_[hidden])

My head hurts from working on this! I just realized <omp.h> is for
OpenMP, not OpenMPI. So, of course the PGI <omp.h> is used. I still
don't know why otfprofile is failing, but at least that explains why
OpenMPI-1.5rc5 has no <mpi.h>.

Sorry for the noise.
