Install on Caldera 2.2.5

Hi, Postgres guru,

I am new to Postgres and just downloaded the source to compile on my
Caldera 2.2.5. I got a trouble and here is what i did (follwoing the
INTALL file):

Hardware : Pentium 200 with 32M ram, 2.1G HD(Linux partition)

1)Add a new account postgres
2)make dir /usr/scr/pgsql ; /usr/local/pgsql and changed
ownership/group to postgres through root
3) cd /usr/src/pgsql and unzipped the source achive
4)cd /usr/src/pgsql/postgres-6.5.3/src and run
./configure --with-template=linux_i386 --without-CXX
make all >make.log 2>&1 &

the make failed (see attachement) !!
make.log

NB:
I downloaded bison1.28 and compiled /installed successfully.

I changed Makefile.global to have:
YFLAGS= -y -d
YACC= /usr/local/bin/bison

I also changed Makefile.custom to have
CFLAGS = -mpentium

Any help is much appreciatted .

Peter
