2025Q2 branch status; wasi-libc

[Benny Siegert <bsiegert%gmail.com@localhost>]

Hi!

Looking at the latest series of bulk builds, I think we are in good
shape to branch. Two things that make me uncomfortable though:

lang/wasi-libc was broken on NetBSD 9/amd64 back in May by the update
of LLVM to version 19. Crucially, this means no Firefox and no
Thunderbird on this platform.
The latest failure was https://releng.netbsd.org/bulktracker/pkg/54419667:

libc-bottom-half/cloudlibc/src/libc/dirent/fdopendir.c:12:6: error:

Any ideas on this one? I cannot even find an explanation of this
compiler error on Google.

The other failure is OpenEXR on i386. This is a regression in the
3.3.3 update from April. The error message is:
