From 0adb124659cfadf9f0b5c99874c476116f0cf74f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Mon, 16 Apr 2012 04:31:11 +0000 Subject: [PATCH] Drop darwin-user MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It's been orphaned, not compiling for a long time and despite Apple's drop of their Rosetta ppc emulation technology with Mac OS X Lion no one has stepped up to fix it. Testing necessary changes wrt QOM'ification thus is impossible, so we might as well remove it completely.
