Description of problem:

Hello there,

I just tried to compile package gnuchess-5.02-9 from Redhat 8.0.

Here are some of the compiler messages.

book.c:83: warning: `wfp' might be used uninitialized in this function
eval.c:658: warning: operation on `c' may be undefined
iterate.c:98: warning: too few arguments for format
players.c:180: warning: `result' might be used uninitialized in this function

Here is a patch which shuts up the compiler.
