question about harddrv.{h,cc}

In the CVS of harddrv.{h,cc}, there are macros for making the class 
completely static.  I realize that this has speed implications when 
there is only one hard drive class that needs to be instantiated.  In 
any case, the following marcos are in mainline CVS:

 #  define BX_HD_SMF  static
 #  define BX_HD_THIS_PTR theHardDrive->
 #  define BX_HD_THIS (theHardDrive)
 #else
 #  define BX_HD_SMF
 #  define BX_HD_THIS_PTR this->
 #  define BX_HD_THIS this->
 #endif

This does not appear consistent with other classes in Bochs that use 
this construct.  Shouldn't BX_HD_THIS be defined as "this" rather than 
"this->"?  Also, functions in harddrv.cc reference "this" directly.  
Shouldn't these functions use BX_HD_THIS instead?

Thanks,
Brian
