--- Comment #6 from emsr at gcc dot gnu.org --- Something like parse_number was in the original doc as an implementation example. The idea was to select the smallest integral type that could accommodate the number string with. This is done with _Select_int. _Select_type picks the most space-efficient duration ratio type using _Select_int.
