The point of wine-preloader is to map memory before glibc is initialized, so we can't call anybody else's code before our own. If your gcc now requires %gs to be initialized, then you use -fno-stack-protector to compile wine-preloader.
I'm using "gcc version 4.1.2 20060814 (prerelease) (Debian 4.1.1-11)" and it works fine for me, so I guess Ubuntu must have broken things somehow.
