Support for MPICH-MX in mpiexec

[Charland, Denis]

Hi Pete,

I went trough the same files today and I found a few modifications that I forgot to make (it was late yesterday). It works now.

I will double check all the config files, Makefiles and the .in files to be sure that all the modifications have been made. Then I will "make distclean" and rebuild again (configure, make and make install) and test.

If everything goes fine, I will generate a patch file with diff to be applied to mpiexec 0.80. I will then apply this patch file to a clean 0.80 distribution, rebuild and test.

Denis

Patrick makes it sound like the changes will be minimal (thanks).
If you can find the time to modify mpiexec's start_tasks.c (grep for
GM) and perhaps gm.c and get it to work, send the patch and I'll
figure out how to merge it in so both GM and MX are supported.
