Build platform - i686 Linux 2.2.14-6.1.1
Target platform - PowerPC 750
>Description:
The libstdc++-v3/gcc build fails for the PowerPC750 cross
compiler on a x86 PC host. I have tried with both the most
recent released version as well as the current CVS version.

The build fails with the following error message:

if [ x"-fPIC" != x ]; then \
  /compilers/BUILD/gcc-obj/gcc/xgcc -B/compilers/BUILD/gcc-obj/gcc/ -B/compilers/ppc/7xx/powerpc-linux/bin/ -c -DHAVE_CONFIG_H -g -O2 -I. -I../../../gcc/libiberty/../include  -W - Wall -Wtraditional -pedantic -fPIC ../../../gcc/libiberty/strerror.c -o pic/strerror.o; \
else true; fi
../../../gcc/libiberty/strerror.c:463: warning: static declaration for `sys_nerr
' follows non-static

dio.h:553: previous declaration of `sys_errlist'
>How-To-Repeat:
1. Following the instructions in the installation instructions,
   I renamed libstdc++ to libstdc++-v2 and libio to libio-v2.
2. I linked the libstdc++-v3 source to the libstdc++ directory
   at the top of the gcc source tree.
3. I have binutils 2.9.5.0.22 built for the powerpc on the x86.
4. I created a directory called gcc-obj and ran the 
   configure script from there :
       configure --host=i386-linux --target=powerpc-linux 
       --program-prefix=powerpc-linux- --with-cpu=750 
       --with-gnu-as --with-gnu-ld --enable-threads=posix 
       --enable-cross --enable-shared --enable-languages=c,c++
       --disable-libgcc-rebuild 
       --with-headers=<My dir containing the linux and glibc header files.>
       --with-newlib
5. Run make.
