7688 # If we're using a separate build tree, set it up now.
7689 # DIRS are directories which we simply mkdir in the build tree;
7690 # LINKS are things to symlink back into the source tree
7691 # (these can be both files and directories).
7692 # Caution: do not add files or directories here using wildcards. This
7693 # will result in problems later if a new file matching the wildcard is
7694 # added to the source tree -- nothing will cause configure to be rerun
7695 # so the build tree will be missing the link back to the new file, and
7696 # tests might fail. Prefer to keep the relevant files in their own
7697 # directory and symlink the directory instead.
7698 # UNLINK is used to remove symlinks from older development versions
7699 # that might get into the way when doing "git update" without doing
7700 # a "make distclean" in between.
