Re: symlinks

Unfortunately that code won't work if toname is of the form FOO/BAR, where FOO is a symbolic link to some other place in the filesystem. The simplest fix is to remove the HAVE_SYMLINK code entirely, and to fail if the hard-link call fails. It's one less thing to configure in Makefile and in private.h. But if you want to support situations where hard links don't work, I think it would be simpler and more portable to make a copy instead of a link.
