    In thinking about this further I can see both solutions (including
    sys/types in standard includes, and using an architectural-type typedef
    and only including the architectural includes).   I think the typedef
    idea is doable but I still worry that it will result in a lot of mess
    in the include files.  #include <sys/types.h> creates more namespace
    pollution but seems to be a whole lot cleaner otherwise.  I don't think
    the typedef idea will completely solve the namespace pollution issue
    because, again, a good chunk of application C code out there needs 
    sys/types.h anyway.  I wonder if there is a way to test its effectiveness
    in regards to reducing ports patches and such (improving portability).

    For the record, I do not think we will hit up against the problem of
    multiple incompatible typedefs, because the typedefs are based on
    architectural types (e.g. like _BSD_TIME_T), not core C types.
