Artifact 93222f0acf3e9398d4c52719cacdcfc5fdbe7ecfc4e2c749341bc7732855292a:

• File src/exceptions/OFSeekFailedException.m — part of check-in [48980f2297] at 2015-11-29 11:43:05 on branch trunk — Make properties a requirement and clean up code

  This increases the required GCC version from 4.0 to 4.6 (exception:
  Apple GCC, which already supports this with >= 4.0 starting with OS X
  10.5). Since even GCC 4.6 is really old by now, there is no point in
  still supporting something even older and making the code ugly because
  of that. While some hardware and OS support was dropped from GCC 4.6
  compared to GCC 4.0, there is nothing in there that would be an
  interesting target with the exception of BeOS maybe - but a port to BeOS
  can also be achieved using the Haiku support. The other dropped OSes are
  mostly old versions of OSes while newer ones are still being supported
  (and those newer versions of those OSes still support the same
  hardware). (user: js, size: 1609) [annotate] [blame] [check-ins using]
