Different vendors have different _IOW macro definitions in their
sys/ioctl.h files, and they differ in whether their first argument
should be a quoted letter or an unquoted letter.  The installed
afs/vice.h file tries to know which one it is, so that it can define
_VICEIOCTL() properly, but it's getting it wrong on your platform.  It
looks like a simple fix to afs/vice.h, that you want the _IOW('V', ...)
formulation rather than the _IOW(V, ....) one.
