That seems illogical, if there's no drive root
specified, paths should be relative to current
directory...

Is "" meant as some 1-byte-saving shortcut for "\"?

Hatari uses same Atari <-> host path resolving
code for all GEMDODS HD functions.

Does "" map to "\" also with:
- Dcreate()
- Ddelete()
- Fcreate()
- Fopen()
- Fdelete()
- Fsfirst()
- Fattrib()
- Frename()
- Pexec()
?

Test program is always nice, even just a binary.
If it's within couple of tens of KB, just attach
it to mail.
