I was suggesting that if you're building with ncurses before 5.9 patch 
date 20110625, it's possible that your application is getting some
definitions from ncurses' term.h which conflict with eCom's definitions
for tcgetattr.

If that's the case, it might improve things to update the ncurses
version to something more recent.  (Caveat - I've not built with
OS/2 EMX since the spring).
