So rather than file a bug and wait, I first tried a newer version of
clang, and clang-15 worked. Hooray!

Here's what I did:

# Become root

sudo -s

# install clang-15

apt remove llvm-14 clang-14 libclang-cpp14 libclang1-14
apt autoremove
apt install clang-15 llvm-15 libclang-cpp15 libclang1-15

# put its binaries in the path - no, there doesn't seem to be a more elegant way

cd /usr/lib/llvm-15/bin
for f in *; do rm -f /usr/bin/$f; ln -s ../lib/llvm-15/bin/$f /usr/bin/$f; done

and then get out of root and ./autogen.sh
