--- Comment #13 from Thomas Henlich <thenlich+gccbug at gmail dot com> ---
Just a minor issue: I think that the sense of the message arguments in calls to
gfc_notify_std() should be inverted - they should describe the feature as
supported in the correct standard, and not as an error message.
For example:
gfc_notify_std (GFC_STD_F2018, "positive width required at %L", &format_locus)
should read
gfc_notify_std (GFC_STD_F2018, "zero width at %L", &format_locus)
It just seems counter-intuitive to read a message like:
gfortran -std=f2008 -o test-f2018.exe test-f2018.f90
2 | write(*, "(e0.10e2)") 0.00314_4
| 1
Error: Fortran 2018: positive width required at (1)
because the user is trying to access a feature (zero width) of Fortran 2018,
but that fails. The current message implies that "Fortran 2018 requires a
positive width" which is exactly the opposite, this is confusing.
