Build failure with --with-x-toolkit=no

[martin rudalics]

When attempting to build master on Debian bookworm with gcc 12.2.0 using

CFLAGS='-O0 -g3 -no-pie -Wno-missing-braces' ../configure 
--with-gif=ifavailable --with-tiff=ifavailable --with-gnutls=no --without-pop 
--enable-gcc-warnings=warn-only --with-x-toolkit=no --enable-checking=yes 
--enable-check-lisp-object-type=yes

I'm currently getting

Any ideas?
