------- Comment #1 from jakub at gcc dot gnu dot org 2010-01-25 12:03 ------- This is completely undocumented attribute, so you first need to get Apple to actually document what it does and get the documentation into doc/extend.texi. Especially nothing explains the relationship between weak attribute, weak_import attribute and #pragma weak. Unless this is clarified, there is nothing that can be done about this, complain to Apple.
