'po_gnatdist' error regarding 'a-sttebu'

When I compile the bank application in the PolyORB examples or my own DSA application I get an error referring to 'a-sttebu.ali' and 'a-sttebu.ads', which I believe is new in GNAT 2022.

I found this 'workaround' ...

In the folder from which po_gnatdist is invoked ...

$ cp /usr/lib/gcc/x86_64-pc-linux-gnu/13.2.1/adainclude/a-sttebu.ads .

$ mkdir --parents dsa/x86_64-unknown-linux-gnu/obj

$ cp /usr/lib/gcc/x86_64-pc-linux-gnu/13.2.1/adalib/a-sttebu.ali dsa/x86_64-unknown-linux-gnu/obj/

I am using Arch linux and GCC '13.2.1'.

I have tried building polyorb with the '-gnat2022' flag in place of '-gnat12', unfortunately to no avail.

The full error messages are ...

Regards.

Start by reproducing the PolyORB examples/dsa/bank failure with po_gnatdist simcity.cfg on GCC 13.2.1, then inspect how po_gnatdist handles a-sttebu.ali and a-sttebu.ads and the generated dsa/x86_64-unknown-linux-gnu/obj directory. Done means the bank application builds without manually copying those files.
