Bugfix - uploading post thumbnails.

#### I was not able to upload post thumbnail or browse my library for thumbnail.

In my errorlog I found:

    PHP Parse error:  syntax error, unexpected '=' in /*wordpressdir*/wp-includes/pomo/translations.php(171) : runtime-created function on line 1

I think it is caused by translation file, because problematic expression was:

    ($n==1  ? ( 0 ) : ( $n%10>=2 && $n%10< =4 && ($n%100<10 or $n%100>=20)  ? ( 1 ) : ( 2)))

You just need to replace **< =** to **<=** and so on.
My locales are **pl_PL**.

I know it's walkaway, but it works! :)
