gcc-3.0 build problems (SuSE-7.1)

[Daniel Rohe <rohe at physik dot RWTH-Aachen dot DE>]

I tried to compile gcc-3.0 on SuSE Linux 7.1 and got the following:


cd /usr/src
mkdir gcc-3.0
mv gcc-3.0.tar.bz2 gcc-3.0
cd gcc-3.0
bunzip2 gcc-3.0.tar.bz2
tar xvf gcc-3.0.tar
mkdir gcc-obj
cd gcc-obj
../gcc-3.0/configure --prefix=/usr/local0
make bootstrap

/usr/bin/gcc -c -DHAVE_CONFIG_H -g -O2 -I.
-I../../gcc-3.0/libiberty/../include  -W -Wall -Wtraditional -pedantic
../../gcc-3.0/libiberty/getpwd.c
In file included from ../../gcc-3.0/libiberty/getpwd.c:7:

make[1]: Leaving directory `/usr/src/gcc-3.0/gcc-obj/libiberty'
make: *** [all-libiberty] Error 2

does anyone know what this means?

cheers,
