TIOCGETC and TIOCGLTC are used in a call to ioctl, so any non-Posix
system is highly unlikely to have them, because Posix-style ioctl is
normally absent there.

I ran the preprocessor of sysdep.c and made sure that the resulting
file does not use any of these 2 on both w32 and MS-DOS.

Yes, you can do that.
