Thanks.
I am using a Linux host with kernel version 4.x for cross building.
It looks like autoconf is not defining the "PGRP_PIPE" macro variable as
there is no check for linux kernel version 4.
I don't see the error " child setpgid (4238 to 4232): Operation not
permitted" after I backport this patch

to bash-4.2
