To Artifact [97ecf45660]:

• File configure.ac — part of check-in [c70fd7d7f3] at 2016-10-08 15:57:45 on branch trunk — Never override CoreFoundations's forward handler

  If an application links ObjFW and (Core)Foundation, overriding
  CoreFoundation's forward handler breaks things.

  Before this commit, this only worked depending on the load order: If
  ObjFW was loaded first, everything was fine, as CoreFoundation would
  just override ObjFW's forward handler. However, if CoreFoundation would
  be loaded first, ObjFW would override CoreFoundation's forward handler
  and break CoreFoundation. (user: js, size: 34242) [annotate] [blame] [check-ins using]
