Could you add a milestone entry for this to packages/gcc/package.desc. I already added an entry to config/arch/nios2.in to handle the removal.

I think the first batch of build failures are due to some ./configure tests failing to pick up the right functions and using bad fall-backs.

@cpackham Could you comment on why the massive ncurses patches are needed? Close to half a million (!) LOC of new patches seems excessive for a compiler upgrade.

Could (some of) these patches be avoided by explicitly using -std=gnu17 when building ncurses? https://gcc.gnu.org/gcc-15/porting_to.html

@tttapa yes it's not just support for GCC15 it's basically ncurses updates since 6.5. I did briefly think about trying to reduce the update to just the fixes for the bool issues we were seeing but I figure there are other fixes in there we probably want too.

I don't think it's quite as bad as it seems. Some of it seems bigger because of the way the patches have been exported so there is a lot more context than a the diff -u3 you'd get out of git. Fedora 42 points at the full source snapshot https://invisible-island.net/archives/ncurses/current/ncurses-6.5-20250426.tgz but that's not part of the GNU mirrors so it's a toss up between carrying those patches or taking away access to the source via the GNU mirrors.

Ran a build-all over the weekend and the only failures were

  - i686-w64-mingw32,nios2-spico-elf
  - mips64-ol9u5-linux-gnu
  - powerpc-unknown-linux-uclibc,m68k-unknown-uclinux-uclibc
  - x86_64-multilib-linux-uclibc,powerpc-unknown-elf

I think the mips64-ol9u5-linux-gnu is pre-existing. I'll create issues for them and attach the build.log
