The Makefile for gnuchess 4.0 pl68 is distributed with the OPT line
for the gnufour ICS client uncommented instead of the "normal" one.
This is a mistake.

The Makefile is also distributed with -DUSEINT defined.  This option
adds the line of code "#define short int" to gnuchess.h, before a
number of system header files are included.  This is totally
brain-dead, and caused me to waste some hours in the debugger; I had
to go down to the assembly-language level before I realized why
isalpha was giving the wrong answer.

The following might work better:

# gnufour ICS client
#
#OPT= -DCACHE -DCLIENT -DGDX -DHASGETTIMEOFDAY -DHISTORY -DNULLMOVE -DQUIETBACKGROUND -DBAREBONES 
# normal
OPT= -DCACHE -DGDX -DHASGETTIMEOFDAY -DHISTORY -DNULLMOVE -DQUIETBACKGROUND -DSEMIQUIETBOOKGEN
