CC not getting -O passed?

When I configure PG using:

CC=cc CXX=CC ./configure  --prefix=/home/ler/pg-test --enable-syslog --with-CXX --with-perl --enable-multibyte
--with-includes=/usr/local/include--with-libs=/usr/local/lib
 

CC doesn't see the -O flag.


CC -g -K PIC -I/usr/local/include -I../../../src/include -I../../../src/interfaces/libpq  -c -o pgconnection.o
pgconnection.cc
CC -g -K PIC -I/usr/local/include -I../../../src/include -I../../../src/interfaces/libpq  -c -o pgdatabase.o
pgdatabase.cc
CC -g -K PIC -I/usr/local/include -I../../../src/include -I../../../src/interfaces/libpq  -c -o pgtransdb.o
pgtransdb.cc
CC -g -K PIC -I/usr/local/include -I../../../src/include -I../../../src/interfaces/libpq  -c -o pgcursordb.o
pgcursordb.cc
CC -g -K PIC -I/usr/local/include -I../../../src/include -I../../../src/interfaces/libpq  -c -o pglobject.o
pglobject.cc
CC -G -Wl,-z,text -o libpq++.so.3.1 pgconnection.o pgdatabase.o pgtransdb.o pgcursordb.o pglobject.o  -L/usr/local/lib
-L../../../src/interfaces/libpq-lpq -Wl,-R/home/ler/pg-test/lib
 

Why?
