different sort order in windows and linux version

I have two postgres servers, one on linux (fedora core 5), one on
windows, both are version 8.1.4.

Both databases are initialized with locale Croatian and win1250 encoding.

running pg_controldata on windows returns this

LC_COLLATE:          Croatian_Croatia.1250
LC_CTYPE:            Croatian_Croatia.1250

the same command on linux returns this

LC_COLLATE:                    hr_HR
LC_CTYPE:                      hr_HR

which is the same, I suppose.

the sample databases are both initialized the same way

CREATE DATABASE sample
  WITH OWNER = postgres
       ENCODING = 'WIN1250'
       TABLESPACE = pg_default;


both databases have the same sample table

CREATE TABLE sample
(
  some_text char(13) NOT NULL
);


when I execute a query 'SELECT SOME_TEXT FROM SAMPLE ORDER BY SOME_TEXT'
I get different sort order on these two servers.

On the left side is windows server sort order, and on the right side is
linux server sort order. all values are left padded with spaces.

The only thing I can think of is that somehow these databases weren't
initialized in the same way, if so what is the difference?

Tnx in advance
