[Pkg-rust-maintainers] Bug#1070241: Bindgen missing dependency on Clang

[Jussi Pakkanen]

Package: bindgen
Version: 0.66.1-4

If you do `apt install bindgen` and try to use it, it will fail with
an error message like this:

/usr/include/zconf.h: 254 fatal error 'stddef.h' not found

Running `apt install clang` makes it work. As bindgen can't be run
without it, the bindgen package should have a dependency on clang (or
whatever other package actually provides the necessary functionality).

Thanks,
