From b388d5e4c6d1054e9876e93e07cf49687ccf5fea Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Fri, 16 Oct 2009 12:35:49 +0000 Subject: Very evil missuse of svn to test if AVOption and AVOption2 are compatible. If this test triggers anywhere for anyone, revert this commit immedeatly. Ill revert this in a day or 2, its just so we know beforehand if the idea with the union is doable or not without breaking ABI/API.
