sgttyb struct not defined

[Ole Streicher <olebole@debian.org>]

Hi,

I am trying to get the latest version of eso-midas [1] running on kfreebsd
(and hurd). The problem is that it makes use of the "sgttyb" struct [2].
When compiling, I get the error

sp_pty.c:94:25: error: variable 'd_sg' has initializer but incomplete type
                 struct  sgttyb d_sg = {

I already tried to #include <sgtty.h>, but it didn't help.

Since I hadn't the problem with the last release (13.09pl1.4), and this
particular file wasn't changed since then, I would suspect that there were
an incompatible change in the last months? How can I get this struct back?

Best regards

Ole
