Sorry -- I didn't mean to imply that we hadn't noticed that 2.2.2 had
been released. I was trying to say that LT 2.2.2 was our gating
factor and that has now been met. We have an outstanding ticket to
upgrade the automated process that builds the official OMPI tarballs
(we have a strictly controlled process that runs in a specific
environment to make official OMPI tarballs -- that's where the upgrade
needs to occur); it just hasn't happened yet. It's marked as a
blocker for the OMPI v1.3 release.
I have been using 2.2.2 on my development cluster since shortly after
it was released (I think other developers are, too).

Wow -- those timings are impressive! Quoting that URL (OMPI is ):
For example, in a large package with 871 substituted variables, of
which 2*136 are produced by AM_CONDITIONAL, and roughly 210 Makefiles.
'./config.status' execution for those Makefiles (no headers, no

Is the "with the Autoconf patch below" equivalent to AM 1.10 + AC 2.62?
