Translations do not work on AMD64

[szotsaki]

Even tough I installed the Hungarian language pack correctly (copied into the languages folder and changed the wp-config.php file) Wordpress did not recognise the new settings and used English as its default language.

I figured out (with this post: ​http://wordpress.org/support/topic/36104?replies=3#post-204361) that there is a bug in the wp-includes/gettext.php file.

I had to change a line (+ $magic == $MAGIC1) and everything works fine!

Here is the patch:

szotsaki, can you see if the patch in #3780 works for you? If so this issue has been fixed on trunk.

Yes, it must be work.
The diff (​http://trac.wordpress.org/attachment/ticket/3780/gettext-64-without-bitwise-ops.diff) uses the $magic == $MAGIC1 which is the essence of my solution.

Thus I mark this bug as duplicate.
