tmm tries to do a very different job; msdos.c just emulates the few
relevant Xlib functions.

Yes, they are supported, but it's not msdos.c that does it, it's
xmenu.c.  Look in single_menu_item there, around line 635, and you
will see that it shows "[X]" for toggles and "(*)" for radio buttons.

IOW, what we have for the non-toolkit build on X already does a large
part of the job, so that only the actual display of the menus is
missing.  And that is where we can lift most of the code from msdos.c,
as I wrote earlier.  The only _real_ problem with that is that msdos.c
gets mouse events via system calls in plain C, whereas text terminals
use Lisp code in t-mouse.el or some such, and it might be tricky to
call Lisp during menu display.

If I had time to write the code, I'd do it a long time ago.  But
thanks for volunteering, maybe someone else will step forward for the
coding job (after the release, of course).
