Already did that. The scrips then goes like this:

  echo "($0) building botstrap GCC"
  make all-gcc install-gcc LANGUAGES="c c++"
  cerror "GCC build failed"

  mkdir -p ../${newlibbase}
  cd ../${newlibbase}

  echo "($0) configuring newlib"
  ../../source/${newlibbase}/configure \
     -v --quiet --prefix=$prefix --disable-newlib-supplied-syscalls \
     --target=${target} --enable-interwork --enable-multilib \
     --with-gnu-ld --with-gnu-as
  cerror "newlib configuration failed"

  echo "($0) building newlib"
  make all install #clean
  cerror "newlib build failed"

  cd $prefix/source
  cd ../build/${gcccore}
  echo "($0) building GCC"
  make all install LANGUAGES="c c++"
  cerror "GCC build failed"

All goes well until de final build of GCC. Then I get this error:

Any suggestions? The only difference to GNU ARM guide are the patches:

gcc-3.4.3/gcc/config/arm/t-arm-elf

-# MULTILIB_OPTIONS    += mno-thumb-interwork/mthumb-interwork
-# MULTILIB_DIRNAMES   += normal interwork
-# MULTILIB_EXCEPTIONS += *mapcs-26/*mthumb-interwork*
+MULTILIB_OPTIONS    += mno-thumb-interwork/mthumb-interwork
+MULTILIB_DIRNAMES   += normal interwork
+MULTILIB_EXCEPTIONS += *mapcs-26/*mthumb-interwork*

I've read in a number of GCC foruns that this is necessary to enable 
interworking.

The other patch is:

newlib-1.13.0/Makefile.in
-CFLAGS_FOR_TARGET = -O2 $(CFLAGS)
+CFLAGS_FOR_TARGET = -O2 $(CFLAGS) -DREENTRANT_SYSCALLS_PROVIDED 
-DNO_FLOATING_POINT -mthumb -mthumb-interwork

Which is supposed to disable floating point support and to enable thumb and 
interword in newlib.

Today Fortune tells us:
I am getting into abstract painting.  Real abstract -- no brush, no canvas,
I just think about it.  I just went to an art museum where all of the art
was done by children.  All the paintings were hung on refrigerators.
