Problem when testing ncurses 5.2 on a LynxOS system...

[Frédéric BOITEUX]

        Hello,

  I'm trying to use the ncurses 5.2 package on a (fresh) LynxOS (PowerPC) 
system.
After few modifications to be able to build it,
I've tested it and I've some problems :
Test programs like 'gdc', or 'firework' don't run correctly, for example with
the firework program, instead of printing an explosion in the middle of the 
screen like :


                                          +++ 
                                         ++#++
                                         +# #+
                                         ++#++
                                          +++ 

I get the first line ok, the following lines are on the left of the screen, 
like :



                                          +++ 
++#++                                      - 
+# #+                                      -
++#++
 +++ 


For my test, I've used an rxvt terminal, run on a Linux PC server(with Debian),
 with a telnet on the LynxOS machine.
I've compiled and tested the same ncurses library on the PC, with the same 
terminal config (TERM=rxvt),
and it works !

I wonder where to look for solving my problem ?

        Thanks for any advice,

                Frédéric Boiteux.
