V6.10a can't use double DPTR feature

Can anybody verify that the double DPTR featue in the C library does not work? The ?COPY2 function is missing from the library. I can assign a struct to another struct when the double DPTR option is not enabled, but when enabled, the linker compilains that it can't find ?COPY2 (which uses two DPTR I assume). Also memcpy(..) does not work.
