This would be wrong, especially on arches where u_md is nonempty because the kernel will supply user structs with u_md in them. The problem is moot in -current since u_md went away. struct mdproc has also become nonempty on i386's, but there is now an empty struct mdthread to break compiling with -ansi at least in the kernel (-pedantic is also needed for breakage; -ansi alone works and this is tested a lot since the kernel is always compiled with it).
