Artifact 3ae679cd77c9c2548577559ae5941f322d4c864fa58a2a9c8abd2cea463cfb60:

• File src/OFTimer.m — part of check-in [13ee56edf3] at 2014-06-21 21:43:43 on branch trunk — Move all macros from OFObject.h to macros.h

  This means that OFObject.h imports macros.h now, making it unnecessary
  to manually import macros.h in almost every file. And while at it, also
  import autorelease.h in OFObject.h, so that this doesn't need to be
  manually imported in almost every file as well. (user: js, size: 10245) [annotate] [blame] [check-ins using]
