Fails to translate struct with unnamed union field.

Tried translating this [clay.h](https://github.com/nicbarker/clay/blob/main/clay.h). C2V thinks it finished successfully, but this is in the output.

```v
struct Clay_SizingAxis { 
	size Union (unnamed union at /Users/adamoates/.vmodules/vclay/src/clay.h
	type_ Clay__SizingType
}
```
