Recent versions of GNU Chess source tar ball exclude the opening
book.

gnuchess-5.05.tar.gz should be 164851 bytes.

gnuchess-5.04.tar.gz was around 159Kb, so it has grown by about
2Kb.

$ md5sum gnuchess-5.05.tar.gz 
008820142c414517512ab0ad3e036c8b gnuchess-5.05.tar.gz

Download and install like any other GNU project tar ball.

tar xvzf gnuchess-5.05.tar.gz
cd chess
./configure
make
"become root 'su' on Linux"
make install { or cp gnuchess.exe C:\...winboard
directory....\gnuches5.exe for Winboard under Cygwin}

A prebuilt executable (gnuches5.exe) suitable for Winboard is
available currently at http://www.wretched.demon.co.uk/R505,
which can just replace the executable for GNU Chess of the same
name that comes with Winboard.

If you are upgrading very old versions of 5, you will need to
recreate the book.dat file from the PGN file. If you are using a
recent version of 5 (like 5.04) recreating the opening book will
create a smaller opening book with less depth to it, but keeping
the old opening book is perfectly fine.

 Hope that helps,
