   Thanks for chasing that down.

   This one looks pretty simple and depends only on vsnprintf, which has   
   been in VMS since 7.3-2, so it was probably in some ancient standard,   
   though I haven't looked yet:   
      
   https://github.com/jkaivo/asprintf/blob/asprintf/asprintf.h   
      
   It's MIT which I think can be included in a GPL project like FreeTDS. I   
   will try to remember to look at this when I get some other things sorted   
   out.
