I noticed that with my later machines, "sys/termio.h" is gone -- only
"sys/termios.h" exists.

Yeah, the include error would not be affected by this.

Please change the "#include <sys/termio.h>" to "#include <sys/termios.h>"
(in both places, just to be safe) in system.h.  And then try the above
changes.

BTW, I just tried recompiling rk under my later machine (the one running
Linux 2.4.19) and it worked.  According to dpkg, the version of libncurses
is 5.2.20020112a-7 (whatever that means!).  And, strangely, libtermcap* is
linked to libncurses.

I noticed that the Makefile has:

# following options for Solaris
#LIBS=-lcurses
#LINTFLAGS=
#CDEBUGFLAGS=-Xs -g
#CDEBUGFLAGS=-Xs -O

Did you try uncommenting the above lines out?

I assume that you ran it on the Linux machine.

That's too bad that it doesn't work.  The low-level ioctl() tty interface
must be different on your machine.  I'm not sure why that would be.  I'll
try to do some research.
