That sounds as if the environment stack size _could_ theoretically be 
specified in the Ada source, for the Janus/Ada compiler to export to the 
Janus/Ada binder, which would then set it in the .OBJ for the Windws 
linker. Still we would need a standard way (a pragma or aspect, no 
doubt) to specify the size in the Ada source. That way is currently 
missing, AFAIK.
