Fails to build on Fedora "v4l2_pix_format_union_(anonymous_at_/usr/include/linux/videodev2_h_500_2)" is not a valid Ident #95

When I try to build v4l2-sys-mit v0.2.0 on Fedora it fails with the error below. I have tried in a clean Fedora container with the same results. Works in a Ubuntu container.

You could try bumping bindgen to the latest upstream version and see whether this helps. Which version of Fedora is this, by the way?

The latest version works (v4l2-sys-mit v0.3.0). It was just 0.2.0 that did not build. I just need to push my dependency to update this dependency then. I'm consuming v4l2-sys-mit via nokhwa :)

I run the latest Fedora (39) btw.

Thas was apparently already brought up in https://github.com/l1npengtul/nokhwa/issues/147. Sorry for the noise!
