further research:

my Linux box with these droppings: redhat 6.0
my Linux box without these droppings: mandrake 7.0

on both boxes, the generated configure is bad

  echo $ac_n "checking for POLLIN in
#include <poll.h>
#include <sys/poll.h>  ""... $ac_c" 1>&AC_FD_MSG
echo "configure:8758: checking for POLLIN in
#include <poll.h>
#include <sys/poll.h>  " >&AC_FD_CC
if eval "test \"\${ac_cv_define_POLLIN+set}\" = set"; then
  echo $ac_n "(cached) $ac_c" 1>&6

O.k....  On the box without the droppings, if I start bash via
/bin/sh, echo "gobble" 1>&GOBBLE won't create such droppings but if I
start it via /bin/bash it *will*.  That bash is 2.03.  The bash which
always creates droppings is 1.14.

This should explain why you don't get the droppings and I do.

Nothing (yet) explains why we have >&AC_FD_MSG in configure in the
first place :(
