I think the feature that allows importing c, called "importC", is newer than 5 years. I think they may have "copied" it from Zig :D they definitely are trying to not "fall behind" Zig and keep making the language better. With DMD, you can cross compile just as with Zig, but only to object files as the linker is not multi-platform... so I am experimenting with using Zig's linker to "finish" the job. Unfortunately, Zig is not being able to link Phobos, the D stdlib, for reasons I don't understand yet.
