• File src/macros.h — part of check-in [c1fe4b2b77] at 2020-07-12 09:49:35 on branch trunk — Make of_random() a function

  When arc4random() is unavailable, either random() or rand() is used and
  both need to be seeded. If of_random() is a macro, it needs to be
  (re)seeded every time, as it's unknown whether it has already been
  seeded. As it is seeded with gettimeofday() due to the lack of a better
  initial seed, this means every call returns the first state for the
  current time, which is very predictable. random() and rand() are both
  not cryptographic, but this should at least make it a little bit better
  now. (user: js, size: 21483) [annotate] [blame] [check-ins using] [more...]

• File src/macros.h — part of check-in [ef614a225d] at 2020-09-26 21:58:39 on branch trunk — Don't require __COUNTER__ for OF_RESERVE_IVARS

  __COUNTER__ does not exist in GCC 4.2, and Apple GCC 4.2 is still the
  newest compiler available for macOS 10.5. (user: js, size: 21485) [annotate] [blame] [check-ins using]
