Problem 823

We try to install the library geant4 (version 7.1.p01) on our IBM SP4 computer
(AIX 5.2), and specially the gate software (version 1.2.0).

At the compilation of one of the gate module (src/GateMuonPhysics.cc), we have a
problem. The problem came from the file
source/processes/hadronic/models/de_excitation/fermi_breakup/include/G4FermiFragmentsPool.hh,
and specially from this line :
   std::multimap<const std::pair<G4int,G4int>, const G4VFermiFragment*,
  		 std::less<const std::pair<G4int,G4int> > >::iterator

We have to correct the programm (suppress the const attribute) :
std::multimap<std::pair<G4int,G4int>, const G4VFermiFragment*,
		 std::less<std::pair<G4int,G4int> > >::iterator

We reproduce this on an simple example. This example works if we use the g++
compiler (Compaq Linux), not with the c++ compiler (c++) of our NEC SX5, not
with the xlC compiler of our IBM SP4.

IBM_SP4 : more map.C
#include <map>

using namespace std;

main()
{
  multimap<const pair<int,int>, const int> iterator;
  // Correction multimap<pair<int,int>, const int> iterator;
  return 0;

}
