+ 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
