communication with Cute Chess and Arena doesn't work on Linux

[tsoj]

To get it to work (only for Arena) I needed to add fflush(stdout); after this line

cpw-engine/com.cpp

Line 330 in 2054969

printf("%s\n",command);

.

Cute Chess gives this error Could not initialize player cpw: no response to ping

I compiled with g++ *.cpp -O3 -DNDEBUG -o cpw

Thanks !
I also needed to add this line to compile a working CPW-Engine (v1.1.18) for SCID .. without that line, the initialisation took "too long" according to a SCID message and the engine could not be added to SCID !
However, the same binary does NOT work in CuteChess GUI (i did not test the Cli) : after 15 seconds a message comes ""no response to ping".
I'm on Xubuntu 20.04.
