It depends not only on the host but also on the file system. Even on Linux and Solaris, "ln -s" doesn't work on vfat and smb filesystems. I doubt that saving one Makefile line here is worth yet another autoconf test and possibly trouble on HP-UX. I'm satisfied with the "cp" and "mv" commands: it works everywhere and doesn't need an autoconf test. Bruno
