Did you specify the -ieee option? From cxx manpage:

 -ieee
   Support all portable features of the IEEE Standard for Binary
   Floating-Point Arithmetic (ANSI/IEEE Standard 754-1985), including
   the treatment of denormalized numbers, NaNs, infinities, and the
   handling of error cases. This flag also sets the _IEEE_FP macro.
   To flush floating point underflows to zero, add the
   -underflow_to_zero option.
