* include/hbcomp.h
   * source/compiler/harbour.c
     + Added: char hb_comp_cCastType

   * source/compiler/harbour.y
     ! Optimized AsType
     + Added: support for type casting like: Var := FunCal() AS ... and, return Var AS ...
     /* Todo: add support for Array[n] := ... AS ..., and oVar:Data := ... AS ... */

   * source/compiler/hbpcode.c
     + Added type casting support to:
       HB_P_POPLOCAL
       HB_P_POPLOCALNEAR
       HB_P_POPMEMVAR
       HB_P_POPSTATIC
       HB_P_RETVALUE

   * include/hbclass.ch
     + Added type casting to resolve Strong Type warnings:
       return s_oClass:Instance() AS CLASS _CLASS_NAME_
       local Self AS CLASS <ClassName> := QSelf() AS CLASS <ClassName>

   /* Note: Strong Type code, and Class code, should compile with upto -w4, without [invalid] Strong Type warnings. */
