I just wanted to rant a little about complaints. You can leave these in if you want, but IME complaints are useless. I don't think we've ever seen anyone fix a compiler bug on the basis of a complaint being issued. And, I also don't recall ever debugging some user problem by enabling complaints -- if a bug gets to that point, I'm invariably debugging the reader. That is, they're just noise. Now, it might still be good to have a checker for DWARF and presumably for CTF. But IMO that should be a separate tool. And for CTF it doesn't even seem hard to do, given that these errors are coming straight from it. thanks for listening, Tom
