Looks good to me. However:

In the test case, could you also add a "PR fortran/36534" to the
as comment?

Additionally, I wonder whether instead of the name-based checking
+	  && (sym->name[0] != '_' || sym->name[1] != '_'))
it wouldn't be cleaner to check
          && sym->attr.intrinsic
(If you change it to attr.intrinsic, you need to set
the attribute also in intrinsic.c's gfc_convert_type_warn.)

I know that using __... names it not really possible in Fortran (except as C
binding name), but - still - I think it is cleaner. But I am fine with
either version.
