Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #16 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Note, what is most important with this are configure scripts, if we start warning on something still widely used in configure snippets, we'll get silently different results of configure checks. For old style definitions, the question is if we want to warn about void foo () {} style of functions or just those which actually have some arguments.
