Failed to update Fedora 17 due to dependency problem

I have a problem updating Fedora 17. When I try yum distro-sync - it
fails with dependency error. When I add --skip-broken option, it also
fails to resolve dependencies. What should I do to upgrade my system?
Why there are packages marked x86-32? Isn't it too early for this ABI to
be introduced in F17?

Here is what yum says in first case:

--> Running transaction check
---> Package libstdc++-devel.i686 0:4.7.0-5.fc17 will be installed
--> Processing Dependency: libstdc++(x86-32) = 4.7.0-5.fc17 for package:
---> Package libstdc++-devel.x86_64 0:4.7.0-5.fc17 will be updated
--> Finished Dependency Resolution
Error: Package: libstdc++-devel-4.7.0-5.fc17.i686 (fedora)
           Requires: libstdc++(x86-32) = 4.7.0-5.fc17
           Removing: libstdc++-4.7.0-5.fc17.i686 (@fedora)
               libstdc++(x86-32) = 4.7.0-5.fc17
           Updated By: libstdc++-4.7.2-2.fc17.i686 (updates)
               libstdc++(x86-32) = 4.7.2-2.fc17
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

When I add --skip-broken as suggested yum fails with following error:

Error:  Multilib version problems found. This often means that the root
       cause is something else and multilib version checking is just
       pointing it that there is a problem. Eg.:
         1. You have an upgrade for libgfortran which is missing some
            dependency that another package requires. Yum is trying to
            solve this by installing an older version of libgfortran of the
            different architecture. If you exclude the bad architecture
            yum will tell you what the root cause is (which package
            requires what).
         2. You have multiple architectures of libgfortran installed, but
            yum can only see an upgrade for one of those arcitectures.
            If you don't want/need both architectures anymore then you
            can remove the one with the missing update and everything
            will work.
         3. You have duplicate versions of libgfortran installed already.
            You can use "yum check" to get yum show these errors.
     can also use --setopt=protected_multilib=false to remove
       this checking, however this is almost never the correct thing to
       do as something else is very likely to go wrong (often causing
       much more problems).
