You no longer have to remove the libf2c directory. The language options are taken care of by the configure option --enable-languages. eg. --enable-languages="c,c++".

You need to have the installed cross-binutils in your path. Try "export PATH=/usr/local/cross-gcc/target/bin:$PATH" to prepend the path. Regards, Brendan Simon. ------ Want more information?
