/* WORKAROUND pr80556:
   For x86_64 Darwin10 and later, the unwinder is in libunwind (redirected
   from libSystem).  This doesn't use the keymgr (see keymgr.c) and therefore
   the calls that libgcc makes to obtain the KEYMGR_GCC3_DW2_OBJ_LIST are not
   updated to include new images, and might not even be valid for a single
   image.
   Therefore, for 64b exes at least, we must use the libunwind implementation,
   even when static-libgcc is specified.  We put libSystem first so that
   unwinder symbols are satisfied from there. */
