dosdevices/c not present.. how is it created?

[Roger Cruz]

I'm getting the following error when running Wine.

err:process:init_windows_dirs directory L"C:\windows" could not be created, error 2
err:process:init_windows_dirs directory L"C:\windows\system32" could not be created, error 3

Using the debugger, I think I found where the problem is:

2140            int fd = open( unix_name, O_RDONLY | O_DIRECTORY );
(gdb) p unix_name
$25 = 0x4040b2e8 "/data/winehome/dosdevices/c:"
(gdb) n
2141            if (fd != -1)
(gdb) p fd
$26 = -1
(gdb) where

export WINEPREFIX=/data/winehome

When I look in my $WINEPREFIX directory, I can see that the c: directory is not there

# ls /data/winehome
system.reg
dosdevices
drive_c
user.reg
# ls /data/winehome/dosdevices
#

How does that c: directory get created and by whom?  I have deleted the $WINEPREFIX several times already to no avail.

Thanks
