Uhm, the current lv package in Fedora and Debian uses it:

#ifdef HAVE_SIGVEC
   struct sigvec sigVec;

   sigVec.sv_handler = WindowChangeHandler;
   sigVec.sv_mask = sigmask( SIGWINCH );
   sigVec.sv_flags = SV_INTERRUPT;
   sigvec( SIGWINCH, &sigVec, NULL );

   sigVec.sv_handler = InterruptHandler;
   sigVec.sv_mask = sigmask( SIGINT );
   sigVec.sv_flags = SV_INTERRUPT;
   sigvec( SIGINT, &sigVec, NULL );
#else
# ifdef SIGWINCH
   signal( SIGWINCH, WindowChangeHandler );
# endif
   signal( SIGINT, InterruptHandler );
#endif /* HAVE_SIGVEC */

HAVE_SIGVEC is true, and the first conditional is active.
