Syntax:

           /V2

  The /V2 qualifier causes the compiler to use the CDD V2.0 defaults for
  the signs of the fixed point numbers.  With this qualifier, BYTE, WORD,
  and LONGWORD datatypes are unsigned by default, but QUADWORD and
  OCTAWORD datatypes are signed.

  If you do not specify the /V2 qualifier, all the fixed point datatypes
  are unsigned by default.
