This is non-portable, I think on two counts:

 . the assumption that the exit code is the signal number left-shifted
   by N bits (btw, isn't N = 8, not 7?)
 . the assumption that SIGPIPE is signal 13 (does Posix mandate that?)

What do we expect to happen here on MS-Windows and other non-Posix
platforms, where both of the above assumptions are false?
