GetDriveType and empty CD/DVD-ROM drives

I'm currently working on bug #17037.
The root cause is that GetDriveType("D:\") (if D is mapped to
/dev/cdrom) returns DRIVE_NO_ROOT_DIR while on Windows it returns
DRIVE_CDROM when there is no disc in the D drive.
GetDriveType tries to open D:\ which is converted into \\??\\D:\\ then
The fact is that there is a dosdevices/d:: file (symlinked to
/dev/cdrom) but no dosdevices/d: except if a CD or DVD is in and mounted
The conversion \\??\\D:\\ -> ~/.wine/dosdevices/d:/ is done in
wine_nt_to_unix_file_name (ntdll/directory.c, line 2897).
I'm asking here because I wonder if modifying wine_nt_to_unix_file_name
is the right thing to do and sane: it's called at several locations and
I don't want to cause trouble and regressions, well, if possible.
Thanks for any advice
