Then I think we already found the bug. On Macs, if there exists a directory 
'doc' then this is the same as 'dOc', 'DOC' etc. from the system's view (not the 
filesystem's view).

The filesystem saves upper and lower case letter files/directories correctly, 
but for accessing these files/directories I can mix upper and lower case letters 
like I want. For example,

   /tmp Thomas$ ls -l
   /tmp Thomas$ mkdir MyDir
   /tmp Thomas$ ls -l
   total 0
   drwxr-xr-x   2 Thomas  wheel  68 Mar  8 21:42 MyDir
   /tmp Thomas$ cd mydir
   /tmp/mydir Thomas$ cd ..
   /tmp Thomas$ cd MYDIR
   /tmp/MYDIR Thomas$ cd ..
   /tmp Thomas$ ls -l
   total 0
   drwxr-xr-x   2 Thomas  wheel  68 Mar  8 21:42 MyDir
   /tmp Thomas$

Ie. once again, you cannot create a 'DOC' file if a 'doc' directory already 
exists. I expect 'DOC' should either become something else or we need special 
tretments on Macs.
