[sles-beta] SLES11-SP3 RC1 question concerning zypper dist-upgrade when upgrading from SLES11-SP2, why additional 32bit libraries on a x86_64 bit server?

[urs.frey at post.ch]

Hi

I am doing SLES11-SP3 upgrade testing from SLES11-SP2 x86_64 to SLES11-SP3 RC1 x86_64
I installed SLES11-SP2 base pattern, to latest patch-update

When invoking zipper dist-upgrade, I can see that some new packages get installed. So far OK.
What worries me, that there are new libraries-32 being installed.
I mean, when having a pure x86_64 SLES11-SP2 64bit installation, why get 32bit libraries newly installed?
So is there any idea why I get libgcc43-32bit & libgcc_s1-32bit & libstdc++43-32bit & libstdc++6-32bit 32bit libraries in addition?

Here what I see when issuing : /usr/bin/zypper --non-interactive dist-upgrade --auto-agree-with-licenses
