PR target/47558 * config/darwin10.h (LINK_GCC_C_SEQUENCE_SPEC): Put -lSystem first on 10.6 and later to ensure that we always use the unwinder from the system. Only add -no_compact_unwind when tarteting darwin 10.6 or later. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@169905 138bc75d-0d04-0410-961f-82ee72b054a4
