compiled for me; I had to make some more changes to make it work for
me (see attached patch):



3. the AC_DEFINE's for the new OMPI_* macros in mpi.h were at the very
beginning of, before the various $ac_cv_<foo> shell
variables had any values (hence, the resulting #defines were empty).
I moved them to the end of

The only one that concerns me is #3 -- Brian: was there a reason you
put those AC_DEFINE's at the top of

Given that the previous patch must have somehow compiled for Brian,
I'd like to get a review before this is committed to the trunk. I
tested on x86_64 RHEL4U4 and OS X Leopard and my amended patch seems
to work. Can someone else verify that the attached patch works for
them before I commit?
