New icc and iomanip problem

Create a file named /etc/profile.d/intel.sh (or whatever you like, but with .sh extension), which contains:

source /opt/intel/composerxe/bin/compilervars.sh intel64
alias icpc="icpc -std=c++0x"

This will both set up the environment and solve the problem.
This is related to Fedora 14, g++ 4.5+, and icpc 12.
