Hi,

I created the attached patches to solve some problems with java.io.File
and java.io.FileDescriptor.

1. fix the handling of files of the form
     java.io.File("//") java.io.File("///") ...
   in private String normalizePath(String p)

2. fix
     java.io.File("").getAbsolutePath()
   to return
     System.getProperty("user.dir")
   instead of
     System.getProperty("user.dir") + separatorChar

3. fix java.io.File.getCanonicalPath()

   The previous implementation didn't handle cases, where a leading part of
   the path contained symlinks and the trailing part didn't exist.

4. fix the encoding of file names.

   Suns jdk uses the default enconding System.getProperty("file.encoding")
   for file names. libgcj used to use UTF8. This causes major trouble, if
   you have file-names containing ISO 8859-1 encoded german Umlautes (äöü).

The patch was developed and tested on a Linux system only. I read the
instructions on the GNU GCC home page about submitting patches and know,
that my patch doesn't follow the coding standards at all. Unfortunately I
have no time to reformat the patch and divide it into independent pieces.
Nevertheless I hope the patch will be of some value.

Best Regards
  Anselm Kruis
