When I build my application on windows, I get the following warnings coming from GEANT4. Maybe they should be reported to get them fixed? /afs/cern.ch/sw/geant4/releases/share/geant4.3.0/include\G4PiMinusAbsorption AtRest.hh(65) : warning C4800: 'int' : forcing value to bo ol 'true' or 'false' (performance warning) /afs/cern.ch/sw/geant4/releases/share/geant4.3.0/include\G4KaonMinusAbsorpti onAtRest.hh(63) : warning C4800: 'int' : forcing value to bool 'true' or 'false' (performance warning)
I believe that this problem has been fixed in release 4.0.
