This was a good hint and worked. I commented-out the following lines
(5930-5992) in netperf-2.4.2 configure script:

#echo "$as_me:$LINENO: checking whether setpgrp takes no argument" >&5
#echo $ECHO_N "checking whether setpgrp takes no argument... $ECHO_C" >&6
#if test "${ac_cv_func_setpgrp_void+set}" = set; then
#  echo $ECHO_N "(cached) $ECHO_C" >&6
#else
#  if test "$cross_compiling" = yes; then
#  { { echo "$as_me:$LINENO: error: cannot check setpgrp when cross
compiling" >&5
#echo "$as_me: error: cannot check setpgrp when cross compiling" >&2;}
#   { (exit 1); exit 1; }; }
#else
#  cat >conftest.$ac_ext <<_ACEOF
#/* confdefs.h.  */
#_ACEOF
#cat confdefs.h >>conftest.$ac_ext
#cat >>conftest.$ac_ext <<_ACEOF
#/* end confdefs.h.  */
##if HAVE_UNISTD_H

#int
#main ()
#{
#/* If this system has a BSD-style setpgrp which takes arguments,
#  setpgrp(1, 1) will fail with ESRCH and return -1, in that case
#  exit successfully. */
#  exit (setpgrp (1,1) == -1 ? 0 : 1);
#  ;
#  return 0;
#}
#_ACEOF
#rm -f conftest$ac_exeext
#if { (eval echo "$as_me:$LINENO: \"$ac_link\"") >&5
#  (eval $ac_link) 2>&5
