-/* Calls to these functions are generated by the Go frontend for

- complex division expects slightly different results from the GCC
- default. When dividing NaN+1.0i / 0+0i, Go expects NaN+NaNi but
- GCC generates NaN+Infi. NaN+Infi seems wrong seems the rules of
- C99 Annex G specify that if either side of a complex number is Inf,
- the the whole number is Inf, but an operation involving NaN ought
- to result in NaN, not Inf. */
