It is not GCC's business to force developers of packages to get their act together. It is the business of those package developers themselves. GCC should give those developers effective and convenient means of detecting any unsafe and dubious code and of correcting it as they see fit. Which GCC already does by emitting warnings. GCC should only error out if it is completely unable to produce valid code, which is not the case here, since it has been producing valid code for ages. It is a disservice to GCC users if a program that compiled yesterday and worked perfectly well suddenly cannot be built because GCC was upgraded, perhaps due to completely unrelated reasons. It would be a grave mistake on the part of GCC to decide that part of its mission is to teach package developers how to write their code and when and how to modify it.
