Sigh - I failed to tell how I built my compiler:

I used the following configure line:

../trunk/configure -v --enable-languages=c,c++ --prefix=/usr/local/gcc-head --enable-shared --with-system-zlib --without-included-gettext --enable-threads=posix --disable-nls --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --enable-mpfr --with-tune=i686 --enable-checking=release i686-linux-gnu --enable-concept-checks --enable-bootstrap

Note the i686-linux-gnu target.

I have tried building it for i486-linux-gnu with the same result.
Additionally I have built it natively (i686-linux-gnu) using

../trunk/configure   --prefix=/usr/local/gcc-head --enable-__cxa_atexit --disable-nls --disable-checking --enable-concept-checks --with-system-zlib --verbose --enable-languages=c,c++

with the same result.

The make target is bootstrap in all cases.
