There is no real reason not to be using C99 (or C11) unless you work with targets that only have an "ANSI" compiler. The additions that come with each new standard are either sorely needed (stdint.h, stdatomic.h, etc.) or conservative to a fault (_Generic) so you can't even complain about bloat. Down with "ANSI" C fetishism.
