   It turns out tds_vasprtintf already uses vsnprintf if HAVE_VSNPRINTF is   
   defined and only falls back to the /dev/null hack if not:   
      
   https://github.com/FreeTDS/freetds/blob/master/src/replacements/vasprintf.c   
      
   So my next change to FreeTDS will look something like this:

   That should cover everybody with a VMS system from recent decades.
