gtk2 2.10.4 i386 package with i686 folder name

[Vnpenguin]

Hi all,
In devel repo, I see package gtk2-2.10.4-4.fc6.i386.rpm. The content
of this package:

/etc/gtk-2.0
/etc/gtk-2.0/i686-redhat-linux-gnu
/usr/bin/gdk-pixbuf-query-loaders-32
/usr/bin/gtk-demo
/usr/bin/gtk-query-immodules-2.0-32
/usr/bin/gtk-update-icon-cache
/usr/bin/update-gdk-pixbuf-loaders
/usr/bin/update-gtk-immodules
/usr/lib/gtk-2.0
/usr/lib/gtk-2.0/2.10.0
...

My question: why there is "/etc/gtk-2.0/i686-redhat-linux-gnu" here
instead of "/etc/gtk-2.0/i386-redhat-linux-gnu" like previous release
?

Thanks,
