yes - it can be hard distinguishing between versions of curses (as you
may see from the macros I've written for tin/lynx).  I do have a QNX
to experiment with, but haven't been on it recently.  (ncurses does
build, but there is some problem with the linker - it prefers using
the system's shared libraries rather than the static ones I prefer
for testing - but libtool does have that case addressed).

The code (further down in that module) was and'ing KEY_RESIZE with 0xff,
which made it equal ^Z, and consequently interpreted as SIGTSTP.  I don't
think it was apparent before - my recollection is that MC was using its
own signal handler.  (Perhaps a bug in the way I set it up - ncurses
sigwinch was probably active, otherwise I wouldn't have gotten that
problem).

ok - then I probably have time to revisit it.  That was the xterm mouse
(I had configured without gpm, to simplify debugging).  The cursor keys
work properly (but that was surprising since ESCDELAY is set to 0 - so
I still have a couple of unanswered questions).  The original report that
got me looking at MC is that running the editor on FreeBSD produces some
screen trash.
