Root and Geant 4.0.1 with STL

Dear ROOTer,

thanks to Rene Bruns advice concerning the libNew, the 'package'
Geant4 and Root runs well together. Now there is a new version
of Geant4 which offers the possiblity to use the Standard Template
Library instead of the commercial Tools.h++. Since the plan is, as it 
is stated on the Geant webpage, to drop the support for Tools.h++ 
in the next release, I tried out the STL support. 
I got the following problem:

/usr/local/GEANT4/geant4.0.1/source/global/STLInterface/rw/tvhdict.h: In
function unsigned int Hash(const class TString &)':
/usr/local/GEANT4/geant4.0.1/source/global/STLInterface/rw/tvhdict.h:21:
previous non-function declaration template <class K> class Hash<K>'
In file included from /usr/local/root/2.22/src/TList.h:23,
                 from /usr/local/root/2.22/src/TNamed.h:23,
		 from /usr/local/root/2.22/src/TDirectory.h:17,
		 from /usr/local/root/2.22/src/TFile.h:17,
		 from src/PWOEventAction.cc:32:
/usr/local/root/2.22/src/TString.h:318: conflicts with function declaration
unsigned int Hash(const class TString &)'
/usr/local/GEANT4/geant4.0.1/source/global/STLInterface/rw/tvhdict.h: In
function unsigned int Hash(const class TString *)':
/usr/local/GEANT4/geant4.0.1/source/global/STLInterface/rw/tvhdict.h:21:
previous non-function declaration template <class K> class Hash<K>'
/usr/local/root/2.22/src/TString.h:319: conflicts with function declaration
unsigned int Hash(const class TString *)'

This seems to me a deeper problem and I fear that there is no
easy solution, rather than a workaround (which is not necessary at
the moment, because the Tools.h++ version still works fine).
I just want to know, what do you think about this conflict?

Best regards,
Volker
