This namespace (libc vs. ast) collision comes from Olga having added |
_GNU_SOURCE| to our build flags. But IMO it might be wise to rename
the ast src/cmd/re/ed.c |splice()| to something else to avoid hitting
this in the future...
Glenn: Offtopic: is Linux splice(2) somehow useable within libast or
AST tee(1) ?

SPLICE(2) Linux Programmer's Manual SPLICE(2)
NAME
splice - splice data to/from a pipe
SYNOPSIS
#define _GNU_SOURCE
#include <fcntl.h>
ssize_t splice(int fd_in, loff_t *off_in, int fd_out,
loff_t *off_out, size_t len, unsigned int flags);
DESCRIPTION
splice() moves data between two file descriptors without
copying between kernel address space and user address
space. It transfers up to len bytes of data from the file
descriptor fd_in to the file descriptor fd_out, where one
of the descriptors must refer to a pipe.
