problems when building gcc 3.2.3 as crosscompiler

[<t152 at vmars dot tuwien dot ac dot at>]

Hi,

I'm currently trying to build the gcc 3.2.3 as cross-compiler
for power pc on a i686-pc-linux-gnu host with this compiler:

---------8<-------------------8<---------
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113)
---------8<-------------------8<---------

first I have installed binutils 2.13.2.1 with the following
commands:

---------8<-------------------8<---------
mkdir build
cd build
../configure --prefix=/usr/local/gcc323-ppc --target=ppc-pc-linux-gnu
make
su
make install
---------8<-------------------8<---------

then I have tried to build the gcc
with the following commands:

---------8<-------------------8<---------
mkdir build
cd build
../configure --prefix=/usr/local/gcc323-ppc --target=ppc-pc-linux-gnu
make
---------8<-------------------8<---------

after a while "make" terminated with the following ...

---------8<-------------------8<---------

... although the file "signal.h" is, e.g. on
/usr/src/linux/include/linux/signal.h

after commenting out line 21 (# include "rs6000/linux.h") in
build/gcc/tconfig.h make terminated some times later with
the following:

Maybe there is something completely wrong with my approach.

Any hint is appreciated.
