ompi/). - There's still a handful of places that have orte/ #include files; still need to clean those up - A lot of places still use ompi/include/constants.h -- those need to be converted over to use OPAL_ return codes and then switch to the opal constants.h. This commit is the first few steps towards that... This commit was SVN r6843.
