bison problem building inn-2.4.1

Hi,

I'm trying to build inn-2.4.1 on solaris 8 running on a sun sparc system.
Solaris 8 is patched with Maintenance Update 7 and the Recommended Patch
Cluster of 3/10/2004.  I am using gcc v2.95.3, bison v1.875d and perl
v5.8.3.

I configured inn with:  ./configure --prefix=/opt/news --with-perl

Make proceed fine until parsedate.y:

...
gcc -g -O2 -I../include   -c md5.c
gcc -g -O2 -I../include   -c messages.c
gcc -g -O2 -I../include   -c mmap.c
Expect 6 shift/reduce conflicts
bison -y parsedate.y
conflicts: 6 shift/reduce
make[1]: *** [parsedate.c] Broken Pipe
make[1]: Leaving directory `/sw/inn-2.4.1/lib'
make: *** [all-lib] Error 2

Running bison from the command line produced:
root at ef-3:22 bison -y parsedate.y
conflicts: 6 shift/reduce
root at ef-3:23: echo $?
141

man -s2 intro skips error number 141 as does /usr/include/errno.h.

Running bison -v -y produced the following y.output:

State 6 conflicts: 1 shift/reduce
State 8 conflicts: 1 shift/reduce
State 16 conflicts: 1 shift/reduce
State 24 conflicts: 1 shift/reduce
State 30 conflicts: 1 shift/reduce
State 40 conflicts: 1 shift/reduce
