- Note: mpich now builds libmpi.so instead of libmpich.so
- define both -DMPICH_SKIP_MPICXX and -DOMPI_SKIP_MPICXX regardless of
using openmpi or mpich. This simplifies the files and does not harm.
- place wmkdep and dirToString executables under
utilbin/$(WM_ARCH)$(WM_COMPILER).
This helps somewhat when copying rules about, and might help when creating
general rules.
