building arm-elf with newlib

[AKubbat <Akubbat at necelam dot com>]

Hello

I have tried to build arm-elf cross-compiler and use Bills Gatliff's
script and the following components to build a version of ARM-ELF
(using newlib) :
BINUTILSDISTO=binutils-2.15
GCCDISTO=gcc-2.95.3
NEWLIBDISTO=newlib-1.11.0

Host : Redhat 9, i686, latest patches.
Host   gcc version 3.3.2, 


It compiles all the way, but when building the final GCC, it fails with
the following error :

...

I'm not sure why this is happening. But it is reproducible.
I assumed 2.95.3 to be stable and also arm-elf is not an exotic target.
Some search and I found that when I change --enable-languages=c,c++ to 
--enable-languages=c the compilation ends successfully.

Any explanation on what goes wrong when adding C++ support.
The same happens when I want to build a arm-elf version of GCC 3.2.2
and GCC3.3.2.
In those cases the error message is the same (see below)

BINUTILSDISTO=binutils-2.15

Disabling "c++" in languages and this problem disappears
Any hint on what I'm doing wrong appreciated
