Compile/Link Error for Postgres 8.1.0 on Solaris 8

Hello,

I tried to compile Postgres 8.1.0 from the source tar file with
following options:

./configure --without-readline --enable-thread-safety CFLAGS=-xO4
-D_REENTRANT -xipo -mt -lpthread
CC=/export/home/uxapps/workshop/SUNWspro/bin/cc

I am getting following error:

gmake -C ../../src/timezone all
gmake[3]: Entering directory
`/home/rbhide/utilities/postgres-8.1/postgresql-8.1.0/src/timezone'
/usr/ccs/bin/ld -r -o SUBSYS.o localtime.o strftime.o pgtz.o
