Here is my configure:

./configure --target=powerpc-unknown-linux --prefix=/home/davidw/crossgcc --with-libs=/home/davidw/crossgcc/usr/lib/ --with-includes=/home/davidw/crossgcc/usr/include/
 
I put libc6-dev stuff under /home/davidw/crossgcc/

It does not work.

I tried adding the 'host' and 'build' options, but they don't make any
difference.

It fails with:

Any ideas? Thanks:-)
