You're absolutely right; I'd not thought about the orthogonality between what
the library should do and how the compiler should behave. I agree that the
patch is correct; go ahead check it in.

I was also trying to raise the issue of whether we think the warning is
useful.
If it's not practical to avoid the warning in the library, then I wonder if
it's practical to avoid it

Well I didn't want to reopen a discussion which I considered closed. But yes, I
also agree. And in case, we should have the change in 4_3-branch too.

And, by the way, I'm noticing the hard way that return by reference is the most
annoying case: if you want to suppress the warnings still deal appropriately
with references, it's a huge special casing

is probably worth warning about, but maybe we ought to just skip this
warning when instantiating a template function. In other words, warn at
the point of original declaration

Ah, I didn't consider this option! Seems also trivial to implement, just
remove
completely the pt.c version of the warning and keep the one in decl.c. Then,
over the next hours, if I

Thanks Tom. In fact, yesterday I was writing without remembering my past
analyses of this type of issue, with system header warnings not suppressed:
TREE_NO_WARNING is *not* generically uses for that.

Doug, I'm sorry, can you have a look to this one too? I'm slightly confused, we
have PR 36052, and then PR 30601, ... Seems that the warning is intended?!? Do
we have to change bind?!?

By the way, apparently, even after the fix for c++/32256 and c++/32368,
warnings keep coming from inside the system headers... Any idea why, Tom?
Another case would be this one:

Or this pure C++ case is really just a missing TREE_NO_WARNING set somewhere
(check_return_expr?)

My guess is that comment #3 is the right theory, because
this warning is issued from the front end. I did not
investigate deeply though.
