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...
