gcc. You need to reconfigure and rebuild the cross-tools to have this change take effect. Note that from now on it is no longer possible to use the native BeOS compiler to build Haiku. You'll have to build a cross compiler, too. I haven't tested whether this works at all, though. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24542 a95241bf-73f2-0310-859d-f6bbb57e9c96
