Have you considered just writing code to decide if a pair of `\r?\n`s 
has been seen instead of using a more complicated RS? For example, using 
the default RS and ORS, I think this will do what you want:

   --------
   $ cat tst.awk
   $0 ~ /^\r?$/ {
        gotRS = 1
        lineNr = 0
   }
   !gotRS {
        # just keep appending to the record until the real RS is found
        rec = ( ++lineNr == 1 ? "" : rec ORS) $0
        next
   }
   {
        # we have a complete record so save it in $0 and process as normal
        gotRS = 0
        $0 = rec
        print "<" $0 ">"
   }
   --------
   $ awk -f tst.awk
   1
   2

   <1
   2>
   3

   <3>
   --------
