Hi all...

While I haven't looked at the code this refers to
myself, it seems to me that a lot of these warnings
are probably related to private functions put in place
to support public functionality that is not yet
implemented.  Is this the case?

Marek, while we are adding new compiler warnings, can
we have some way to "hide" the warnings on an
individual symbol basis?  It seems to me that our goal
should be to get rid of all warnings one way or
another.  If the warning is coming up because we
haven't used a function we know we will use later,
it'd be nice to attach an attribute to that function,
for instance, that tells our compiler not to show a
warning when this function is private and unused.  If,
on the other hand, we messed up and just ended up
having a private symbol that we wont use, it'd be nice
to get a message on that one.

It seems to me that just turning off the warnings
doesn't help much in these "partial development"

What do you guys think?
