    Change defn of _XOPEN_SOURCE to at least 500.
    
    Without this, Ubuntu 18.04's stdlib.h won't define the pty functions
    (grantpt, unlockpt etc), so they get implicitly declared as returning
    int, which goes horribly wrong when the actual pointer returned from
    ptsname doesn't fit in an int.

    Add an error check for ptsname.
    
    Just in case it returns NULL, we should report that usefully rather
    than proceeding to dereference it.
    
    (I noticed this while debugging the problem in the previous commit,
    though in fact the pointer _wasn't_ NULL.)

    Squash compiler warning for write() in signal handlers.
    
    We don't actually want to do anything with the error, but gcc
    complains if we haven't at least tested it in _some_ way.
