I have a 2-year-old Zaurus somewhere.  I think that Sharp may have
stopped selling them in the US, but there seems to still be an
active developer community.

OTOH, lugging an almost-portable G5 iMac around builds character (or
so I'm told ...)

The bug seems to involve expanding calls to INLINE functions that take
keyword args; that involves a call into the kernel (_SPdestbind1),
where there's a whole bunch of PPC64 code that's suspiciously missing.

I'll try to fix this in an hour or so; I -think- that the bug's
entirely in the kernel, but I'll try to double-check that.
