[cfe-dev] Warn on invalid fp-to-int conversions?

[Krzysztof Parzyszek via cfe-dev]

Hi,
Consider this program:

#include <math.h>
int foo() {
   int a = (int)INFINITY;
   int b = (int)NAN;
   return a+b;
}

It compiles without warnings (using -Wall), however neither of the 
conversions will result in anything useful. Would it be reasonable to 
have a warning about these kinds of conversions?
