Obsolescence of a (now) rarely used interface set aside, something
went wrong in this part of compat reorg:

  * the prototype is no longer available through <signal.h>
  * SV_INTERRUPT _is_ documented in sigvec(2), albeit the NOTES
    section's backward compatibility warning looks funny in light
    of the recent reorg.
