Artifact 2cb1c686e3bbb3d6fd9b6f48fee5be0ee9a195b192dbf25b4ee4dd419e3a01bc:

• File src/OFSystemInfo.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: 6250) [annotate] [blame] [check-ins using]
