Indeed, but please bare in mind that GCC may not be the author's normal 
"everyday" compiler, and since -Wshadow isn't on by default (and isn't 
warned about by most other compilers) they may simply not be aware of the 
issue.  That and an ever shifting number of warnings when new compiler 
releases come out.  I suggest you file bug reports regarding any problems 
you find: if the fix is trivial and they come with patches even better.

While I try to keep my stuff warning clean with MSVC and GCC, but after than 
all bets are off.  Certainly for compilers like Intel's that output pages 
and pages of "notes" that aren't even actual warnings :-(

John.
