[patch/rfc] mention C++ support in NEWS

[David Carlton]

I'm pretty much done merging in my C++ changes (I'll post another
message with more details in a sec), so it seems like it's time to
mention it in NEWS.  Any suggested improvements to the wording in the
following patch?

IMHO, this text is okay, but perhaps it will sound much more useful if
you add some examples of situations where GDB previously didn't work,
and now does.

Yes, I think this would be nice.  OTOH, I'm willig to approve it as
posted too.  Up to you, David.

That's a good point.  How about:

  GDB's support for nested types and namespaces in C++ has been
  improved, especially if you use the DWARF 2 debugging format.  (This
  is the default for recent versions of GCC on most platforms.)
  Specifically, if you have a class "Inner" defined within a class or
  namespace "Outer", then GDB realizes that the class's name is
  "Outer::Inner", not simply "Inner".  This should greatly reduce the
  frequency of complaints about not finding RTTI symbols.  In
  addition, if you are stopped at inside of a function defined within
  a namespace, GDB modifies its name lookup accordingly.

I'm still not entirely thrilled with it, especially that last
sentence; I don't want to go into _too_ many details, but I'm not sure
I've found the right balance.

I'm also trying to think of what else has changed - the patches have
been long enough that I would think I'd be able to point to more
features, but I guess it really is the case that fixing names of types
and teaching GDB about namespaces simply required a lot of
infrastructure changes...

This is okay with me.

I think your text strikes the right balance, one that is appropriate
to NEWS.
