My point is that numeric_limits<> is correctly set for integer types;
so if you're seeing the same problem there, then it ought to be
something different.

As for floating point type, GCC didn't provide fulll support until
3.3. So, I'm having hard time to see where you're driving at.
Before relying on the value of numeric_limits<double>::infinity, you
ought to check for the value of numeric_limits<double>::has_infinity.
