- Fully support REAL*N, INTEGER*N, and COMPLEX*N in the MPI_Op
reduction operations.
- Update ddt to fully support these types as well, to include using
the results of sizes and alignments determined by configure
- Discover the goodness of m4 and consolidate a LOT of configure code
(i.e., remove a lot of essentially duplicated code and
m4-subroutine-ize it). The big kicker was figuring out how to
parameterize AC_DEFINE_UNQUOTED, which you can do if you use m4
properly.
- If we don't support a given INTEGER*N, REAL*N, or COMPLEX*N, don't
error. Just set the right flags so that we don't support them in
the MPI layer.
