compile error on ver. 2.1.6

[dharmin]

Hi

I am running Solaris 8 on SunFire V100 , with following installed :-
 - gcc-3.3.2   ; - m4-1.4   ; - bison-1.875   ; - flex-2.5.4a  ; - 
Berkley db-4.2.52   ;   - openssl-0.9.7d

When compiling cfengine version 2.1.6 , configure sees everything
above and when run make , see below error ....................

/bin/bash ../ylwrap cfparse.y y.tab.c cfparse.c y.tab.h cfparse.h
y.output cfparse.output -- bison -y  -d
got /var/tmp/cfengine-2\.1\.6/src/
M4sugar requires GNU M4. Install it before installing M4sugar or
set the M4 environment variable to its path name.../ylwrap: line 82: 
5212 Broken Pipe             $prog ${1+"$@"} "$input"

*** Error code 1
make: Fatal error: Command failed for target `check-recursive'
seine $ pwd

Can someone please advice on how to resolve the above error.

Apreciate your help.
