Yes, this works... I upgraded a sacrificial laptop.  FIFOs never worked
anyway and every test that should pass does.  If stout-heartedness
prevails, we may produce a 4.2.4 with this fix and the fix for the
-nt/-ot test problem.

If you apply this to 4.2.3, you'll need autoconf 2.5x.  Otherwise you
can cheat by doctoring configure by hand...

After the lines at around 14722:

echo "$as_me:$LINENO: checking if named FIFOs work" >&5
echo $ECHO_N "checking if named FIFOs work... $ECHO_C" >&6
if test "${zsh_cv_sys_fifo+set}" = set; then
  echo $ECHO_N "(cached) $ECHO_C" >&6
else

insert:

  if test "$host_os" = cygwin; then
zsh_cv_sys_fifo=no
else

and insert an extra

fi

(there should already be two) before the lines at the end of the same block:

echo "$as_me:$LINENO: result: $zsh_cv_sys_fifo" >&5
echo "${ECHO_T}$zsh_cv_sys_fifo" >&6
