>Description:

csh from base, as well as tcsh from pkgsrc, both trigger the compat shim in
our libc that issues a __sigaction_sigtramp() call with version = 1 due
to SA_SIGINFO not being set in the sigaction.

>How-To-Repeat:
Use a kernel not providing the v1 trampoline, watch it print
"invalid version 1" when running (t)csh.

>Fix:
n/a
