Ok. How about -cxxlib-icc option then?
$cat sizes.cpp
#include <iostream>
using namespace std;
int main() {
cout << sizeof(char) << "\n";
cout << sizeof(int) << "\n";
cout << sizeof(float) << "\n";
cout << sizeof(double) << "\n";
}
$icc -I /opt/intel_cc_80/include/c++/ -cxxlib-icc sizes.cpp
$./a.out

Dont know if it works for you. But worth giving a try.

Raju et al - here's what I get (below)... ie by adding -cxxlib-icc (no
need for the -I/...intel.../lib) it does indeed work. So what is this
telling us? I guess it's saying all the stuff is there but plain 'icc'
doesn't know where to look (but I thought it should!)
