[Joel Brobecker <brobecker at adacore dot com>]

Hello,

I have posted the gdb-6.7.1 release announcement on the GDB website.
Patch is attached.

PS: It took me a long time to update ANNOUNCEMENT because I had to
review all the changes made and remember what they were fixing.
I think I would appreciate some help the next time if all I had
to do was go through the NEWS file. If we make some fixes to the
branch, I think we should document somewhere what they are about
from the user's perspective, and I think the NEWS file is perfect
for that. Right now, if a user wants to know what's different
between 6.7 and 6.7.1, there is only my ANNOUNCEMENT.
