Dwiddling settings.h to #define C_DEBUG 1 makes it so
that, upon exiting dosbox, the terminal window you
started it from has its term settings messed up and
requires a 'reset' command to get it back to normal.
Most specifically, local echo of characters is turned
off, and it also seems to get confused about the width
of the window.
This is with 12/31 CVS, RH Linux 8.
