## a directory before extracting the files, thus becoming unable to
## extract them.
##
## Ignore return result from chmod, because it might give an error
## if we chmod a symlink.
##
## Another nastiness: if the file is unreadable by us, we make it
## readable regardless of the number of links to it.  This only
## happens in perverse cases.
##
## We use $(install_sh) because that is a known-portable way to modify
## the file in place in the source tree.
