gnuchessx fails to run unless gnuchess is available on the path.
It does run if you set PATH=./ (or just run ./gnuchess --xboard, like
gnuchessx does anyway), however if I do this with input redirecting
from /dev/null (either "make < /dev/null" or "./gnuchessx ... <
/dev/null" etc) it still fails in the same old way: prints "Chess"
then exits immediately, no output is generated.
