Hello Jasmine, 

I can see that you are using mingw-w64 sources and you should first asked
on irc.oftc.net
(http://mingw-w64.sourceforge.net/mibbit.html) how to do it because there
is always someone that can help you.
I recommend also to read this :
http://sourceforge.net/apps/trac/mingw-w64/wiki/Cross%20Win32%20and%20Win64%20compiler
Generally mingw-w64 provides also some script to compile their toolchain,
at least
last time I tried there was a script that you could use as an install
guide.
Compiling mingw-w64 is a bit specific because if you try to compile
gcc-4.5 there are some 
details like multilib and you should read their FAQ.
Hope this helps a bit.
