Ugh, yeah, reproduced here. FTR, this platform has
$ gcc --version
gcc (GCC) 15.2.1 20260123 (Red Hat 15.2.1-7)
$ clang --version
clang version 21.1.8 (Fedora 21.1.8-4.fc43)
While this version of clang doesn't like typeof_unqual, it does take
__typeof_unqual__. So maybe we were premature to decide that we
could prefer the typeof_unqual spelling. I can get it to build
if I use __typeof_unqual__.

Per upthread, we don't have bitcode compilation working in the
meson buildsystem, so we aren't trying to invoke clang in that
case.
