These warnings come from groff; the pod input corresponding to the first
warning is

  X<\t> X<\n> X<\r> X<\f> X<\e> X<\a> X<\l> X<\u> X<\L> X<\U> X<\E> X<\Q>
  X<\0> X<\c> X<\N> X<\x>

which results in 

.IX Xref "\t \n \r \f \e \a \l \u \L \U \E \Q \0 \c \N \x"

A small testcase is

 printf '=head1 foo\n\nX<\\n> X<\\r>'|pod2man |groff -man >/dev/null

Russ, would you like a CPAN ticket about this? It still happens
with podlators 2.2.2.
