Re: Likely obsolete pieces of GDB

Thanks to everyone who replied!  I'll collect all the feedback and
revise the list - either next week or after I get back from my
holiday vacation.

I am happy to change the mechanism; I don't like // OBSOLETE either. 
We can't even use the current mechanism for some of these files:
anything not directly corresponding to a target.

To be honest, I'd been thinking about waiting for everyone to agree on
which things to remove, sending a message to gdb-announce, and then
just doing it.  If there were any justifiable complaints at the time of
the next release we could recover targets from CVS history.  I'm sure
not everyone is comfortable with that sudden of an approach, so
using configure for targets for one release is fine with me too.

This is the only file I've seen any objections to that I really wanted
to get rid of, but it looks like you're right.  Do you know which Alpha
configurations are likely to use it, so that we can know when we don't
need it any more?  Maybe it's all the ECOFF ones.
