perhaps compiler (they appear to have delivered the development 20010714
snapshot as "5.2", but I don't recall any problems with mvchgat in that, per
se). It works fine for me on Slackware 8.0 (with ncurses 5.2,
and with ncurses-current).
I installed a copy of Redhat 7.2, but am not done configuring (or fixing) it.
I'll take a quick look at that later today to see if I can reproduce your
problem.
