>Description:
During the configure of shells/zsh, the following is used to test for
working named FIFOs:

#include "confdefs.h"

#include <fcntl.h>
#include <signal.h>
main()
{
	char c;
	int fd;
	int pid, ret;
	unlink("/tmp/fifo$$");
	#ifdef HAVE_MKFIFO
	if(mkfifo("/tmp/fifo$$", 0600) < 0)
	#else
	if(mknod("/tmp/fifo$$", 0010600, 0) < 0)
	#endif
		exit(1);
	pid = fork();
	if(pid < 0)
		exit(1);
	if(pid) {
		fd = open("/tmp/fifo$$", O_RDONLY);
		exit(fd < 0 || read(fd, &c, 1) != 1 || c != 'x');
	}
	fd = open("/tmp/fifo$$", O_WRONLY);
	ret = (fd < 0 || write(fd, "x", 1) < 1);
	unlink("/tmp/fifo$$");
	exit(ret);
}

if mkfifo() is used, the following results:

# ps alx | grep conftest
  0 19465  8200   0   2  0   24   608 fifo     S    p2 0:00.01 ./conftest
  0 19466 19465   1 -22  0    0     0 -        ZW   p2 0:00.00 (conftest)
