Now you can see how Ada people sometimes feel when this happens the other
way around.

OK, let's be more constructive on all sides.

I agree that this entry is not a wonderful one, although you're not
complaining to the right person.

As for containing justification, that's a fundamental disagreement between
the other GCC modules and the Ada front-end: we, Ada people, consider it
fundamental and much more useful to explain *why* a change is made in
a changelog, since it makes it so much easier to track a change afterwards,
rather than having to dig into the gcc list archives, and this is, when
there *is* a message on a gcc list justifying the change.

We've found that the lack of a justification in changelogs in GCC in general
makes it very hard to track failures and understand changes and is very time
consuming, so we're certainly not willing to loose this very important extra
piece of information.

That's not the right place to discuss this pretty fundamental issue anyway,
but I don't think we're going to change our mind on this issue.

Then I guess you are not using punctuation like other people do: there
are two sentences in the changelog, clearly separated by a 'dot' and even
a line break. But I see that you are in fighting mode, so I'd rather not
discuss this further.

Thanks, that's a constructive hint. Is anyone working on this ?
