On my system, starting XBoard with the "xboard" command and trying to
use the gnuchess engine fails with a "broken pipe" error. According to
the engine menu in XBoard, it uses the "-fcp gnuchess" to set gnuchess
as the engine.

What is strange is that if I start XBoard directly with "xboard -fcp gnuchess",
everything works fine.
