Yes, that was my intention. :)

Hi,

I'd propose to have hard copies in place for all implementations
involved, and complement them by links if necessary. This would
eliminate quiet header drift that certain implementations might
experience once in a while.

Best regards.

Alexander

Perhaps you could just link to OMPI's header file -- it's a live copy
of what's in our SVN repository:

https://svn.open-mpi.org/trac/ompi/browser/trunk/ompi/include/mpi.h.in
