I suppose that's formally true ("stdcall" not appearing in the RM), but 
every Ada compiler for Windows that I know of uses "stdcall" for the 
convention name. (Janus/Ada was the only one that didn't initially, and that 
was easily solved. :-) So practically, that's not a portability problem. We 
were able to put the differences into a handful of packages (mostly having 
to do with linking pragmas).
