[petsc-dev] annoying MPI Attribute type warnings

[Barry Smith]

  Satish, 

     Thanks, based on this 

#undef MPICH_DEFINE_ATTR_TYPE_TYPES
#if defined(__has_attribute)
#  if __has_attribute(pointer_with_type_tag) && \
      __has_attribute(type_tag_for_datatype) && \
      !defined(MPICH_NO_ATTR_TYPE_TAGS)


   what about defining MPICH_NO_ATTR_TYPE_TAGS and just turn off this type checking until this gets fixed?

   Everyone, what are your thoughts?

  Barry
