Multilib-capable gcc on 64bit systems

Question

Hello there,
I post this for those who are interested in building 32bit binaries without a chroot.
I just finished building and testing my gcc-multilib package.
It allows you to build 32bit binaries using the -m32 paramter, like this:
> uname -m
x86_64
> g++ -m32 main.cpp
./a.out
I am a 32bit binary!
> file a.out
a.out: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, not stripped
> ldd32 a.out
linux-gate.so.1 => (0xf7f3d000)
libstdc++.so.6 => /usr/lib32/libstdc++.so.6 (0xf7e27000)
libm.so.6 => /lib32/libm.so.6 (0xf7e01000)
libgcc_s.so.1 => /usr/lib32/libgcc_s.so.1 (0xf7de5000)
libc.so.6 => /lib32/libc.so.6 (0xf7c9f000)
/lib32/ld-linux.so.2 (0xf7f3e000)
You can find the AUR package here:
http://aur.archlinux.org/packages.php?ID=28545
But to build it you need a multilib capable gcc, so most of you wont be able to use this.
For you, I have put an already compiled version up, you can find it here:
  [Update]: Fixed a lot of things in the package, now at release 7
  http://timeoutd.org/gcc-multilib-4.4.0- … pkg.tar.gz MD5 1b094d6bb0cbaa56f60b7f31280eb9b4
Vote for the AUR package
Have fun compiling!

Should I add this to the wiki?
Feel free to do it, welcome to the community
Btw, Doesn't know the default built gcc this? On fedora i used this, it's sure with the default.
