[J3] [EXTERNAL] [BULK] Re: Upcoming gfortran 15 will contain an implementation of unsigned numbers

[Clune, Thomas L. (GSFC-6101)]

The history of this feature  has a twist.   There was a paper proposing this feature for F202y and it *passed*.   However, it did not garner the necessary votes to make it onto the proverbial bus for the WG5 list.

Close, but no cigar.

Someone has said unsigned integers are planned for F202Y. I don’t know where they got that idea. I’m too nervous to post on forums, but if someone else thinks it would useful to post a correction, I wouldn’t be opposed!

Thanks,

Hi Jeff,
I strongly encourage gfortran to issue a warning when this option is used that the code is not portable.

It is hidden behind a flag which is marked as experimental, that is enough.
I will certainly not issue a warning for using the -funsigned flag :-)

If people find it useful... well, if it should happen to become a
widely-used extension, that could add some impetus towards
adding it for F203X.

Best regards

    Thomas
