Thanks for the report. I need to see if that's fixed in upstream.

If it is fixed in upstream, I might just update the in-tree version;
otherwise I will just report it to them.

For now you can probably append -Wno-implicit-fallthrough to
EXTRA_CFLAGS_XEN_TOOLS to work around the issue. I don't think that
warning is very important.
