The solution wouldn't happen to be the same as the one for __sco that's
already in Src/system.h, would it?

I suppose not, since it seems to be the opposite problem.

} include term.h, or by undefining VINTR before including curses.h.  Any
} ideas on what is a good, portable solution?

I suppose we can insert <termio.h> between the #includes of <curses.h> and
<term.h> in terminfo.c (relative to my patch in 13968), but my concern is
that including both <termio.h> (there) and <termios.h> (from system.h) will
choke on some other operating system.

} Can we stomache adding this before the curses.h include:
} 
} # ifdef VINTR
} #  undef VINTR
} # endif

If that's isolated to Src/Modules/terminfo.c, I don't see any reason why
not.
 
} On a slightly related note, anyone know what the "offsetof" define is
} doing in system.h?  It doesn't appear to be used anywhere, and the new
} include of term.h causes it to be redefined (on Solaris).

It's not in the 3.0 sources, but it's been in the 3.1 sources for as long
as I've been keeping track of them (which is only since 3.1.4, I guess).

Might as well #undef offsetof at the same time as #undef VINTR.

Here's another shot at a complete patch (including what was in 13968):
