Comment 10 for bug 948938

The problem is that the patch doesn't allow for any acceleration or clipping that X normally supplies, so it is unlikely to be committed.

If you are having trouble building wine on ubuntu 12.04, there are some workarounds you can try that I detailed in https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/949606. One of them is to install all the i386 dev libraries that you need, even though it breaks amd64 compilation (you can reverse the process afterwards).
