Document Win32 symlink behaviour; adjust tests to take it into a/c. src/ChangeLog addition: 2008-05-21 Aidan Kehoe <kehoea@parhasard.net> * fileio.c (Fmake_symbolic_link): Document behaviour when the underlying OS doesn't support symbolic links. tests/ChangeLog addition: 2008-05-21 Aidan Kehoe <kehoea@parhasard.net> * automated/mule-tests.el (featurep): Make sure that working symlinks are available before testing their functionality. Also, don't bomb out on deleting the other temporary files if deleting the first threw an error.
