I just downloaded the icc and compiles gnubg with it (though I'm not
sure that I did everything right). icc is in /opt/intel/bin, I did
an symbolic link /home/ace/local/bin/gcc pointing to
/opt/intel/bin/icc. gcc --vesion indeed shows "8.0". I put
/opt/intel/lib into /etc/ld.so.conf and did a ldconfig.
