Can't compile gcc - libiberty (argv.c) error!

[rdim_outside at softhome dot net]

Hi all, 

Could you please help me with compilation of latest gcc release... 

gcc version is 3.0.4, binutils - 2.12 

Binutils are made and installed without any problem, configure and make
commands are:
[build#]../binutils-2.12/configure --target=xscale-elf --prefix=/xtls
 --exec-prefix=/xtls/H-i686-pc-linux-gnu 

[build#]make -w all install 

After that path with extended with /xtls/H-i686-pc-linux-gnu/bin 

Then gcc itself was configured with: 

[build#]../gcc-3.0.4/configure --target=xscale-elf --prefix=/xtls
 --exec-prefix=/xtls/H-i686-pc-linux-gnu --with-newlib --with-gnu-as
 --with-gnu-ld 

Build fails with error:

What can you recommend? What I'm doing wrong? I need configure it using
"--with-newlib"... 

Many many thanks in advance!
