For GCC >= 3.3 I'd recommend using

# define HUGE_VAL       (__builtin_huge_val())
# define HUGE_VALF      (__builtin_huge_valf())
# define HUGE_VALL      (__builtin_huge_vall())

(as used by glibc) which are usable in static initializers as required by 
the C standard (unlike any version using constant variables).
