Problem building a cross-gcc for arm target

["Igor Trevisan" <igor at bluewind dot it>]

Hello,

     	I am trying to build a cross-compiler for an ARM target but I 
have some problems.
Configuring, building and installing binutils (binutils-2.10) doesn't 
give me any 
problem, but building gcc (gcc-2.95.2) end with the following error
message:

...

make[1]: Leaving directory `/root/mytmp/tmp-gcc/arm-
elf/libiberty'make: *** [all-target-libiberty] Error 2

I'm trying to build the cross-compiler in the /tools/bin
directory and I added it to the PATH.
I saw in the list of FAQ that someone else had a similar problem 
and the suggested solution was to configure the cross gcc with the 
option:

--with-headers=/root/mytmp/newlib-1.8.2/newlib/libc/include

But I tried it without any good news.
Can anyone suggest something else to go on?
Thanks in advance to every good guy that will save my work and 
my patience!
	Igor.
