title: How to install mingw manually?
body: <p>Once I saw gcc version 4 at <a href="http://sourceforge.net/projects/mingw/files/" rel="nofollow noreferrer">sf.net host page</a> of mingw,I managed to download <a href="http://sourceforge.net/projects/mingw/files/GCC%20Version%204/Current%20Release_%20gcc-4.4.0/gcc-full-4.4.0-mingw32-bin-2.tar.lzma/download" rel="nofollow noreferrer">the whole package</a> and install the new package,but it turns out a lot of mistakes(<code>create process error</code>while run gcc and give out non-meaningful code) and Now I have to rollback to the orginal automatical installed version.</p>
  
  <p>My question is: is there anyone have successfully installed the mingw(with gcc v4) manually?</p>
