I just tested this on my project. It works fine on Linux and macOS, but the compilation fails on Windows. I still have to sort out a few other things, so I can't send a fix yet, but it looks like adding @alignCast in a few places should do the trick.

Just pushed a commit that migrates to translate-c from the now-removed @cImport.

Ah, I was compiling against -msvc on windows. I see for -gnu that the asserts against the size of the C structs are tripping, I think this regressed when translate-c switched from clang to aro. This was a related change I made to arocc at the time: Vexu/arocc#897

I'll have to look into what's going on with -gnu translation.

Looks like the -gnu translation does not include the correct align(16), but the msvc one does.
