The currently available package in ubuntu precise does not support multiarch on amd64/i386. While both versions have to be installed in certain situations the -2 version removes the link for the other one.
This affects LP #1012266 and LP #1023184 as well as the mentioned winehq bug #31161

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because the bug has been fixed in the latest development version of Ubuntu - Quantal Quetzal.

This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please do steps 1 and 2 of the SRU Procedure [1] to bring the need to a developer's attention.

* 0~git20110809-2 is not multiarch compatible. This means that currently a mix of amd64 and i386 variants can not be installed simultaneously. This is however required for e.g. wine installations which require a i386 version of mesa and therefore s2tc to be installed.
* The recently released Humble Bundle 5 makes use of the s2tc extension but requires both architecture versions to be installed for different games. See Bug #1012266
* The s2tc postinst/prerm scripts use update-alternatives to allow multiple versions of texture compression extensions to be installed and easy switching between these. The update-alternatives key was not multiarch compatible in -2 which was fixed in -3.
* Currently the following bug reports are related to this sync Bug #1012266 and Bug #1023184


 1. Install libtxc-dxtn-s2tc0 and libtxc-dxtn-s2tc0:i386
 2. Notice that the link /usr/x86_64-linux-gnu/ was removed in favor of /usr/lib/i386-linux-gnu/

[Regression Potential]
* There is really none. On update the the old handle is removed and replaced by new multiarch update-alternatives.
