I think the m68k-*-uclinuxoldabi* and vax-*-vms* cases need to move up to the top of that case statement (duplicating the "not supported" error), to keep that error even in the --enable-obsolete case.
I see tile* targets are referenced in the diff context. They were obsoleted in GCC 8 (and have also been removed from glibc and the Linux kernel), isn't it time to remove them? -- Joseph S. Myers jos...@codesourcery.com
