Well, I do ;)

SUSE 9.0 comes with full biarch toolchain support on AMD64.

Before you start, install additionaly to the default packages:
        glibc-devel-32bit
        freetype2-devel-32bit
        XFree86-devel-32bit
        XFree86-Mesa-devel-32bit
        fontconfig-devel-32bit
        openssl-devel-32bit
        ncurses-devel-32bit
        alsa-32bit
        and any dependend rpms.

Then:
        export LD="ld -m elf_i386"

        CC="gcc -m32" AS="gcc -c -m32" \
        ./configure --prefix=/usr --x-libraries=/usr/X11R6/lib
        make depend all

The -m32 switches gcc to 32bit mode.

If you have arts-devel installed, you might need to patch
dlls/winmm/winearts/Makefile and replace lib64 by lib.

You will also need attached winebuild patch that uses "LD" from the environment.

Ciao, Marcus
