Rebuilding wine-1.5.15 from source rpm

Hi, I had need to rebuild wine from sources in order to apply a patch to get wine to work with the latest LoTRO.

(see here: WineHQ Bugzilla – Bug 31979 – Lord of the Rings Online crashes at startup)

I was able to modify the wine.spec file to include the needed patches and was able successfully rebuild it.

However this is a 64-bit system and it didn’t rebuild the wine-32bit package. What is the proper way to build the wine-32bit package?

I didn’t see a separate spec file for wine-32bit.

I’m using the wine-1.5.15-196.1.src.rpm from here:
Index of /repositories/Emulators:/Wine/openSUSE_11.4/src

thanks in advance

Also I’m on OpenSUSE 11.4.
