Ok, now I have chosen the same prefix: /opt/sparc-canadian-cross

Now I left those statements out.

I have got them both - includes and libs from the native machine and copied 
them to
/opt/sparc-canadian-cross/sparc-solaris/include
and they are found.

Now I still have a problem.

During compilation of libstdc++ for the target in
sparc-solaris/libstdc++-v3/src
I get the following error.

Does anyone know how to solve this?
