Something in part out=E2=80=91of=E2=80=91topic=E2=80=A6

I will finally test the patch you mentioned, because I may have to  =

recompile the compilers to fix GNATBind, as I'm having an issue when  =

`Suppress_Standard_Library` from package `System` is set to `True`; I  =

receive a complaint about an undefined reference to `Is_Elaborated`. See=
ms  =

there is an inconsistency here in GNAT FSF. Explanation: I've found [1],=
  =

which is a patch to drop the generation of the `Is_Elaborated` variable =
 =

when `Suppress_Standard_Library` is `True`, arguing it was never  =

referenced; except this may be not referenced with GNAT GPL or GNAT Pro =
 =

(just guessing), but it is referenced for me with FSF GNAT [2].

So as I will have to disable the patch from [1], I will get an opportuni=
ty  =

to test the patch to `configure` you suggest in the while.


[1]: http://patchwork.ozlabs.org/patch/194962/

[2]: Here is what gets generated by GNATBind from FSF GNAT:

     procedure adafinal is
        procedure s_stalib_adafinal;
        pragma Import (C, s_stalib_adafinal,  =

"system__standard_library__adafinal");
     begin
        if not Is_Elaborated then -- << Here
           return;
        end if;
        Is_Elaborated :=3D False; -- << And here
        s_stalib_adafinal;
     end adafinal;

     procedure adainit is
     begin
        null;

     end adainit;

Then it complains =E2=80=9C"Is_Elaborated" is undefined (more references=
 follow)=E2=80=9D  =

when compiling the files generated by GNATBind.
