Nested separate compilations

[wtwolfe@hubcap.UUCP (Bill Wolfe)]

   I have now run into two compilers which balk at nested separate
   compilations, as per the following example:

      procedure A is

         procedure B is separate;

      begin [...] end A;

      ------------ in another file... ---------------

      separate (A);

      procedure B is

         procedure C is separate;

      begin [...] end B;

      ------------ in another file... ----------------

      separate (A.B);

      procedure C is begin [...] end C;

   Now according to the LRM, 

         subunit ::= [...] proper_body

         proper_body ::= subprogram_body [...]

         subprogram_body ::= [...] declarative_part [...]

         declarative_part ::= [...] later_declarative_item

         later_declarative_item ::= body [...]

         body ::= [...] body_stub

   and so nested separate compilation should be perfectly legal.  If there's
   anything in the LRM prohibiting this, I don't see it.  Is nested separate
   compilation legal?  If so, when will it be incorporated into the ACVC?
