Error assigining dependent value to variable at file scope

I want to make a few read-only variables, at file-scope. A couple of them are dependent on other such variables. A sample code is as follows:

static const double A = 1.0;
static const double B = A/5;
int main(){}

Compiling this gives me the error:

expression must have a constant value

But GCC does not complain. Is this a bug in ICC, or is it GCC that isn't standard compliant?

Is this relevant: ?
