I'm preparing some final things before the runtime merge.  I'd like to 
propose dropping the
   basis-library/config/c/$(TARGET_ARCH)-$(TARGET_OS)
directories from the repository.  The only file in these directories are a 
c-types.sml which is automatically built and copied by the runtime target 
of the top-level Makefile.  Updating all the platforms for the repository 
is a pain, especially when they will be built automatically the next time 
a compile is run on the platform.  The normal user will only ever need 
their host platform file.  Other platforms are better added by the 
bin/add-cross script (which probably needs some attention on the x86_64 
branch anyways).

The only major outstanding issue that I know of is the PackWord<N> 
performance problems, but we seem to be prepared to live with it and we've 
discussed how to fix it.
