Note that I have uploaded the original pkgsrc patch for libgcc/config.host, as it conflicts with both of the other patchsets and therefore must be downloaded separately for non-Darwin platforms.

I am especially interested in (i) whether the homebrew patchset works on Darwin/x86_64 23.*.* (or earlier), and (ii) whether the new patchset works on Darwin/aarch64 24.*.*; although tests with other combinations are of course welcome.  Please report (i) the platform (e.g., uname -a), (ii) the xcode version (xcodebuild -version; just in case it matters), (iii) the patchset actually used, and (iv) whether the build succeeds.

To facilitate testing, I have updated wip/gcc12 to use distribution patches: the homebrew patchset for Darwin <= 23 (now expanded from aarch64 to all Darwin), a new one for Darwin/x86_64 v24, and the original pkgsrc patch for NetBSD et al.

This works for me on NetBSD and Darwin/x86_64 v24, which are all I can test; the latter does not work with lang/gcc12.

The status quo (i.e., lang/gcc12 behavior) should be retained for Darwin/aarch64 <= 23 and NetBSD et al.

It should also work for Darwin/x86_64 <= 23, which may not have worked before, but I’m not sure.

Please checkout the new wip package and test, especially Darwin/x86_64 v23 and Darwin/aarch64 v24, and in comparison to lang/gcc12.

Thanks a lot.

Cheers,
Brook
