Such a function exists, it is called `_fixpath'.  Look up its 
documentation in the library reference.

I would say this looks like a bug in your code.  readdir doesn't do 
anything special for this case.  Please post the shortest program that 
can be used to reproduce this problem.  Or at least describe what files 
are in the ".." directory and what is its full path name.
