>Description:
        compile ukfs.c, notice warning in mknod call, look at header note
        thar rump_sys_mknod uses uint32_t for dev, not dev_t as it is supposed
        to because it uses the prototype of the compat syscall instead of the
        new one.
>How-To-Repeat:
        see above.
>Fix:
        make the declarations use the proper prototypes.
