--- Comment #231 from The Written Word <bugzilla-gcc at thewrittenword dot com> --- (In reply to John Buddery from comment #228) > These patches are for 11.1.0, but should work on earlier versions too. With > this I have a working gcc which I've tested on several large projects. You don't #undef MAKE_DECL_ONE_ONLY in gcc/config/ia64/hpux.h? If you skip it, do you skip it on earlier GCC builds as well?
