 Not sure about amd64, but the mvscanw test command is wrong as it
 always prints the string[] buffer with %s.
 
 Consider
 
   input "50 12\n"
   call2 OK "2" mvscanw 3 5 "%d"
 
 Now, on a big-endian host, say macppc.  mvscanw "%d" will read "50"
 and store "\x00\x00\x00\x32" at the beginning of string[].  When
 string[] is printed with %s, nothing is printed, b/c the first byte is
 NUL.
