The reason I wanted to minimise dependencies on service_runtime was to avoid
awkward-to-maintain dependencies.  If you're copying the same error codes into
here that doesn't help, because that's more stuff to keep in sync. :-)  So can
you do one of the following:
 * either not try reporting any error codes at the moment (NaCl's existing ones
are only slightly useful),
 * or just #include service_runtime/nacl_error_code.h and use those error codes.

Ok, so please let me use nacl_error_code.h for now. I've deleted this file.

+// native_client/src/trusted/service_runtime/nacl_error_code.h in order to
+// split the dependency to the service_runtime.
+// TODO(hidehiko): Once Bare Metal Mode gets stable enough, we should merge
+// these values to nacl_error_code.
