problem with MB ? 6.5.3 under freebsd-elf

Hi,

today I found a problem with MB on freebsd-elf running 6.5.3 - 
I have compiled 6.5.3 with --enable-locale --with-mb=KOI8
and in psql I tried set client_encoding to 'WIN'
but result of simple query looks like 8-bit was stripped. 
The same query works as expected under Linux.
Also, when I tried
select * from t1 where a ~* 'Р';
I got:
ERROR: Can't find right op '~*' for type 25
I'm outside of city and has access only to b/w terminal
without cut'n paste support ( old 286 + dialup ) and I can't
provide more information. Will do this tomorrow.
Oleg

PS. The same weird thing happens even if I 
set client_encoding to 'KOI8'  - native encoding !
