Thanks for catching that.  The change looks fine, except:

Please put the "| sort" inside the parentheses, instead of outside,
so that _AC_CACHE_DUMP expands to a single command rather than a pipeline.
This won't make a difference for the current uses of _AC_CACHE_DUMP
but will make it a bit more robust in the presence of future uses.  E.g.:

      esac |
      sort
   )dnl
