           Summary: Ada.Directories.Delete_File refuses to delete dangling
                    symlinks
           Product: gcc
           Version: 4.4.7

snippet to reproduce the bug

Deleting a dangling symlink with Ada.Directories.Delete_File fails:

# rm asdf; ln -s asdf bsdf && gnatmake symlink_del && ./symlink_del
raised ADA.IO_EXCEPTIONS.NAME_ERROR : file "bsdf" does not exist


If the symlink is not dangling, deleting works well:

# touch asdf && ln -s asdf bsdf && gnatmake symlink_del && ./symlink_del
Deleted Symlink bsdf
