  !!!!!   Look up  "Windows4Root.h"  !!!!!
 
  The problem is that 

                GetObject 

  is defined as 

              cpp MACRO (!!!) 

within some VC++ header files. To see what happens behind the 
scene you may try too see the output of the cpp just before 
the "real" compilation.  

 That "Windows4Root.h" contains the list of "undef" tricks to avoid 
clashes between Root names and Microsoft WIN32 API macro names.
