--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> ---
I have committed:
r12-2431-gb3d4011ba10275fbd5d6ec5a16d5aaebbdfb5d3c
https://gcc.gnu.org/pipermail/gcc-patches/2021-July/575729.html
which should fix most diagnostic issues with character len /= 1 – except for:
* len=0 – in my understanding, that's valid when using a descriptor but not
when passing the argument as address to the byte stream
-> with current patch not rejected.
* const-length > 1 module variables with BIND(C). Those should now be valid
as well, but that was not touched by this patch.
Regarding len=0 and other things, see also thread starting at
https://mailman.j3-fortran.org/pipermail/j3/2021-July/013189.html

Other TODO with regards to things diagnostic in my patch:
* See 'sorry' in the patch and in the testsuite. Namely:
len=* and len=: require an array descriptor, but for
scalars and (len=*, only) for assumed/explicit-size
arrays no descriptor is used. (Hence, the code aborts
with an error)
-> Requires an update both for the call and for the
function type and for the function interface declaration.
* * *
Attached/submitted patch by José: There is a minor overlap to my committed
patch and some overlap to the issues listed above, but I have not sorted it
out, yet.
