/* WG14 N3298: Yes
* Introduce complex literals v. 2
*
* This introduces two suffixes for making complex literals: i and j (and I and
* J), which can be combined in any order with the other floating literal
* suffixes.
*
* We support these suffixes in older language modes as a conforming extension.
* It used to be a GNU extension, but now it's a C2y extension.
