I don't think so.  `movedata' was modelled on its Borland namesake
which accepts two far pointers.  If you want to rename it to
`farmemmove' or some such, you'd need to reverse the source and
destination arguments, to make it consistent with `memmove'.

That would require extensive changes to GCC (and probably GAS as
well).  It doesn't seem like a worthwhile investment of energy,
especially since in C++ you can overload the operator [] with a call
to _far* functions.
