    I haven't found one... I've already searched the AUR for "gcc" and
the only entries that resemble what I need are:
    * http://aur.archlinux.org/packages.php?ID=28545 (gcc-multilib);
    * http://aur.archlinux.org/packages.php?ID=31547 (cross32-gcc);
    But both of them are for crosscompiling an i686 from a x86_64,
while I need the reverse.

    Could you please give me the exact URL from those packages?

    Thanks,
    Ciprian.
