Apparently it is related to TIOCGWINSZ. When HAS_TIOCGWINSZ is defined
we #include sys/termios.h  and sys/ioctl.h. However,

1) we include them after paricast.h. Unfortunately paricast.h include a
larg macro which conflict with the ioctl_arg union field larg on sco unix.

2) we cannot include sys/termios.h _before_ pari.h because it defines
a macro ECHO which conflict with pari ECHO enum value.

So maybe we can include sys/ioctl.h. before pari.h and sys/termios.h
after pari.h, but this is messy. A better fix would be to split es.c
between the part that need pari.h and the part that need sys/termios.h.

In the meantime we could symply #undef larg in es.c just before
including sys/ioctl.h.

Cheers,
Bill.
