problems building GCC 4.0 on Mac OS 10.3 (except for Fortran95)

[Bojan Antonovic <bojan at antonovic dot com>]

preamble:
- I could compile *ALL* versions of GCC 3.4.x on Mac OS 10.3 with 
default tools.
- I could compile GCC 4.0.0 with Fortran95 enabled 
(http://gcc.gnu.org/ml/gcc/2005-04/msg01648.html).
- I changed make to GNU make 3.79.1 according to 
http://gcc.gnu.org/install/prerequisites.html.
- I use GCC 3.4.3.
- I made only bootstraps.

problem:
- I can't build GCC 4.0.0 with make with C+ and Java or with all 
languages, even with GNU make 3.79.1.

The reported problem is:
/usr/bin/libtool: internal link edit command failed
make[4]: *** [libstdc++.la] Error 1
make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-target-libstdc++-v3] Error 2
make: *** [bootstrap] Error 2

I don't know what prerequisits have changed for building GCC 4.0. I 
don't get that smart from the prerequisits page to figure out what and 
where to do or to get. I would like a detailled help to know what I 
should do to build GCC 4.0 at least for C, C++ and Java. And, if, 
possible, show me a successfull build of GCC 4.0 on Mac OS 10.3 with GCC 
3.x, or declared it as unbuildable and therefore as a bug.

greetings
