Can you try to build from latest 4.6 branch SVN?

The bootstrap works for me with:

CC="gcc -m32" ~/gcc-svn/branches/gcc-4_6-branch/configure
--host=i686-pc-linux-gnu --build=i686-pc-linux-gnu --with-arch=i686
--enable-languages=c

and

make -j 8 BOOT_CFLAGS="-O2 -march=pentium3 -pipe" bootstrap-lean

for

gcc version 4.6.4 20130127 (prerelease) [gcc-4_6-branch revision 195496] (GCC)
