Re: [PATCH, ADA, DOC] PR 15479: Crossrefs and links

Hard coding the name is indeed not desirable and should be addressed before
doing this change.

Sounds like a good idea.

No, the ref is indeed to Ada tasks.

That's indeed related. I do not know the state of the Ada specific
documentation in gdb, so this refers to GNAt additions that may not yet be
at the FSF, although will appear at some point if not already.

> OK for trunk and 4.3?

Not in the current form.

I'd suggest resubmitting a patch with the tricky parts left aside for now,
so that 90% of your changes can be OKed. You can then work on the
remaining 10% when you get a chance.
