[Wine] how to patch wine

[tac28]

Could someone please explain to me how to patch wine? I'm trying to play Empire: Total War but I run into the exact problem discussed in the bug thread found in AppDB when searching for Empire: Total War http://bugs.winehq.org/show_bug.cgi?id=18490

It says all i need to do is patch wine with the code provided by some members but i don't know how to do this.  Some one please help me!!

Thanks
