Are TIOCGLTC and TIOCGETC defined on MSDOS and w32?
[very likely, but it would be nice if someone with access to these platforms could check]
If they are not, we can completely remove the following code in systty.h:
#if defined (TIOCGLTC) && !defined (HAVE_TERMIOS)
#define HAVE_LTCHARS
#endif
#if defined (TIOCGETC) && !defined (HAVE_TERMIOS)
#define HAVE_TCHARS
#endif
which would enable remove of more code in other places...

Those are NOT defined on w32.

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.
