Hi Mark,
it is more than just 'X' – also B/O/Z when used as postfix ('AB'Z) are
nonstandard as in general the use outside DATA and a handful of
intrinsic functions. For instance, print *, Z'ABC' is also nonstandard
and affected by -fallow-invalid-boz. (GCC < 10 silently accepted the
latter.)
I also come up with a gcc-10/changes.html wording; however, I am sure
that my wording should be tweaked as well.
See https://gcc.gnu.org/ml/gcc-patches/2020-01/msg00896.html — I
additionally also modified the diagnostic and the documentation;
hopefully, in a sensible way.
Thanks,
Tobias

Is the wording OK?
second attempt this time with attachment!
