Fix from Philippe .

On Windows, the order in which the dictionary global
objects and the TROOT global object are the inverse as that of Linux (this we
have not control over it).

Also, The previous implementation of BuildRealData had a call to
'InheritsFrom(TObject::Class());' which besides giving its result had the
side effect of loading the currently defined typedefs if the class had not
been loaded yet.  Without this side effect, the typedef used in the class
were not present in the ROOT system ...
