[svn-r7789] Purpose:
Bug fix & code cleanups
Description:
Change our use of MPI derived datatypes to not create datatypes with
"0-sized" lengths, which causes the LANL Q machine to hang.
Also, get rid of "prefer MPI derived datatypes" environment variable since
it has no advantage.
Platforms tested:
FreeBSD 4.9 (sleipnir) w & w/o parallel
