To those who know:

I am having trouble compiling xboard-2.1.pl10
on the linux SLS 0.99pl6.
I get the following error messages:

gcc -fwritable-strings -fomit-frame-pointer  -O2 -m486 -DNO_ASM   
  -I/usr/X386/include  -D_POSIX_SOURCE -D_BSD_SOURCE -D_GNU_SOURCE
   -Dlinux  -DFUNCPROTO=11 -DNARROWPROTO -DHAS_GETTIMEOFDAY
   -c parser.c -o parser.o
parser.l:1287: parse error before `1'
parser.l:1295: redefinition of `input'
parser.l:1058: `input' previously defined here
parser.l:1324: redefinition of `yyunput'
parser.l:1015: `yyunput' previously defined here
parser.l: In function `yyunput':
parser.l:1325: argument `ch' doesn't match prototype
parser.l:1325: argument `yytext' doesn't match prototype
make: *** [parser.o] Error 1

I would appreciate help from those who have done
this before.

Thanks in advance,
