Re: [Patch, Fortran] PR 85841: [F2018] reject deleted features
Hi Steve,
thanks for your comments!

Unfortunately I don't have access to SPEC either. Is anyone in a
position to check this?
If it is indeed a problem, I could remove the warning for the F2018
deleted features with default flags (-std=gnu). However, I'd only like
to do that if it's really necessary.

Yes, I agree that it would be a good idea to keep -std=f2008ts as an
alias for f2018 for a while (possibly until the next release, 9.0),
and document is as deprecated. I can take care of removing the
GFC_STD_F2008_TS macro in a follow-up patch.
Actually there is one other thing I do not like about my previous
patch: The duplication of GFC_STD_* flags in gfc_match_stopcode. To
get rid of this, I'm introducing additional macros in libgfortran.h,
see new patch in the attachment. I hope you agree that this is an
improvement. (Again: Regtests cleanly.)
Cheers,
Janus
