| /* The format of struct sigcontext changed between 2.0 and 2.1 kernels. |
| Fortunately 2.0 puts a magic number in the first word and this is not |
| a legal value for `trap_no', so we can tell them apart. */ |
| |
| /* Early 2.2 and 2.3 kernels do not have the `fault_address' member in |
| the sigcontext structure. Unfortunately there is no reliable way |
| to test for its presence and this word will contain garbage for too-old |
| kernels. Versions 2.2.14 and 2.3.35 (plus later versions) are known to |
| include this element. */ |
