     26  1.1  mrg    For x86_64 Darwin10 and later, the unwinder is in libunwind (redirected
     27  1.1  mrg    from libSystem).  This doesn't use the keymgr (see keymgr.c) and therefore
     28  1.1  mrg    the calls that libgcc makes to obtain the KEYMGR_GCC3_DW2_OBJ_LIST are not
     29  1.1  mrg    updated to include new images, and might not even be valid for a single
     30  1.1  mrg    image.
     31  1.1  mrg    Therefore, for 64b exes at least, we must use the libunwind implementation,
     32  1.1  mrg    even when static-libgcc is specified.  We put libSystem first so that
     33  1.1  mrg    unwinder symbols are satisfied from there. */
