Jason Merrill <jason at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu.org --- Comment #31 from Jason Merrill <jason at gcc dot gnu.org> --- (In reply to David Binderman from comment #30) > gcc looks to be a trailer on this issue. It's not about standards conformance, > its about making it easy for users to find bugs. But under GCC it's not a bug, it just works. Clang is welcome to adopt the same semantics. But I'm also happy to accept the patch in comment #17 once it includes testing. And GCC should build with -Wconditionally-supported so we support bootstrapping with compilers that make different choices.
