If you are applying these patches, you'll need to make sure you have
GNU patch v2.5 or later and the latest release against which the
diffs are made.  Some files in the perl distribution have carriage-returns
by design.  You'll need to remove them before you you can apply the
patches.

  % find -name \* -print | xargs perl -pi -e 's/\r$//'

  % patch -p1 -N < diffs/3480
