| /* 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. */ |
