Details:


running mkfifo on macos returns an error


[err, msg] = mkfifo ("/tmp/pippo.fifo", 600);
err
err = -1
msg
msg = Function not implemented



this is strange as mkfifo appears to be detected as present by configure, as
shown by the following lines in config.log


 HAVE_MKFIFO='1'
 HAVE_MKFIFOAT='1'


a consequence of this is that the gnuplot graphics backend is not working
