As there are officially no deleted feature in f2023, maybe use a
slightly different wording? Say "Not allowed in fortran 2023" or
"forbidden in Fortran 2023" or similar?

I skimmed over existing error messages, and since "forbidden" did
not show up and since "Not allowed" exists but not at the beginning
of a message, I found that
"Prohibited in Fortran 2023"
appeared to be a good alternative.
Not being a native speaker, I hope that someone speaks up if this
is not appropriate. And since I do not explicitly verify that part
in the testcase, it can be changed.

I think we can add a comment that F2023 has no deleted feature, but some
more stringent restrictions in f2023 forbid some previously valid code.

F03, F08 and F18 should have GFC_STD_F2023_DEL (and also F03 and F08
should have GFC_STD_F2018_DEL).
Well, these macros do an incremental bitwise-or, so the bit representing
GFC_STD_F2023_DEL is included everywhere. I also ran the testcases with
different -std= options to check.
Ah, yes. I confused the GFC_STD_OPT* values with the GFC_STD_* ones.
OK with this fixed (and the previous comments as you wish), if Steve has
no more comments.
Thanks for the patch.
If there are no further comments, I will commit once I am able to
fully build again with --disable-bootstrap and -march=native ...
Thanks,
Harald
Thanks again.
