Build error: arguments to krun_set_exec are incorrect

[marco-04]

I'm having this build error on Gentoo with rust-bin 1.80.1 and bindgen 0.69.4

error[E0308]: arguments to this function are incorrect

Looking at the definitions of the krun_guest_args and env variables as Vec<*const c_char> it seems that it could be an issue with bindgen, tho I'm not sure. By manually changing the generated bindings, it builds and seems to work fine

@marco-04 I thought it was fixed on libkrun side long ago: containers/libkrun#181

[marco-04]

Unless it's on another branch, cloning the repo and building on main doesn't work for me

I'm an idiot. For some reason I still had around an old libkrun.h header from a dirty installation. I got rid of it and now it works as expected. Thanks for the help!
