Just a friendly word of warning -- this is arguably the worst project to
pick of all the things on the project page (though unfortunately there
is more than one stinker on there).  It's been attempted a couple of
times, had always lead to a lot of contention, etc.

That doesn't mean it can't be done, just that you ought to expect it to
be a pain.

Last time this came up, I think the conclusion was that we'd prefer it
if we could get warnings only for some kinds of shadowing, but not all
kinds.  There was a sense that warnings for shadowing of 'index' was not
very useful.  I remember some discussion of checking for a GCC change in
gdb's configure, but I don't remember the details any more.  They're in
the archives.
