Commit 08f42608 authored by Jon Lech Johansen's avatar Jon Lech Johansen

* ./modules/gui/macosx/aout.m: cleaned up the code, removed intf dep.

  * ./src/misc/darwin_specific.m: fixed segfault (o_enumerator was being
                                  released twice) and memory leak.

    Bonne Ann�e!
