Sorry for not follow the thread and posting from different account
than before. I'm currently having trouble with ishii@postgresql.org
account. Marc is kindly working for me and will be fixed soon but...

No the plaform is not changed. I compare the link command for psql 8.3
and current.

8.3:
gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wendif-labels -fno-strict-aliasing command.o common.o help.o input.o stringutils.o mainloop.o copy.o startup.o prompt.o variables.o large_obj.o print.o describe.o psqlscan.o tab-complete.o mbprint.o dumputils.o ../../../src/backend/parser/keywords.o -L../../../src/port -lpgport -L../../../src/interfaces/libpq -lpq -L../../../src/port -Wl,-rpath,'/usr/local/pgsql/lib' -lpgport -lz -lreadline -lncurses -lcrypt -ldl -lm -o psql

CVS Head:
gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wendif-labels -fno-strict-aliasing command.o common.o help.o input.o stringutils.o mainloop.o copy.o startup.o prompt.o variables.o large_obj.o print.o describe.o psqlscan.o tab-complete.o mbprint.o dumputils.o ../../../src/backend/parser/keywords.o -L../../../src/port -lpgport -L../../../src/interfaces/libpq -lpq -L../../../src/port -Wl,--as-needed -Wl,-rpath,'/usr/local/src/pgsql/current/lib' -lpgport -lz -lreadline -lncurses -lcrypt -ldl -lm -o psql

So the difference seems:

--as-needed -Wl,

is added to CVS Head. Actually if I remove the option and link psql,
then everything is fine. Any idea?
