INFINITY and -pedantic with gcc



Hi,
I have curious bug with gcc and the option -pedantic.
I want to use the value INFINITY defined in math.h. Here is a sample code :
==== test.cpp ====
#include <cmath>
#include <iostream>


using namespace std;

void test_inf(double &x) {
  x = INFINITY;
}

int main() {
  double x;
  test_inf(x);
  cout << x << endl;
}
===========

This code compiles well without the option -pedantic but I want to use the option -pedantic. I want to be sure my code will compile on any platform with gcc. I know that INFINITY is equal to 1e50f and 1e50f is greater than FLT_MAX. The option -pedantic raise this error : floating constant exceeds range of 'float'.
Why I cannot use INFINITY with the option -pedantic?


Thanks

Jasmin
