Hi Pavel,
One thing to consider is where gcc finds your X libraries. Wine knows its on a x86_64 system and supplies the -m32 itself. Of course, you will have to watch out for missing required packages reported by configure (bison, flex libxml2-devel, libxslt-devel, cups-devel, fontforge, freetype2-devel-32bit, zlib-devel-32bit, xorg-x11-devel-32bit, mesa-devel-32bit, hal-devel are the packages I had to add on my SUSE 10.1 system). All I then have to type to build wine is
./configure --x-libraries=/usr/X11R6/lib && make depend && make
then
make install (as root).
