If you use Fedora 15, you can add x32 yum repository:

http://www.kernel.org/pub/linux/libs/glibc/hjl/x32/fedora/15/x86_64/

and install x32 kernel/glibc rpms.  Then you can enable x32 on
GCC trunk.

BTW, I will upload x32 GCC binary for Fedora 15 to

http://www.kernel.org/pub/linux/libs/glibc/hjl/x32/fedora/15/gcc/

It may take a while.

Thanks.
