I will summarize some points which g++ warned.  
  
(1) I fixed following points.  
*Made destructor of ROMEConfig and ROMEDataBase virtual.  
  
*Removed or comment out unused variables.  
    int i                            in ROMEPATH::~ROMEPath()  
    char* defaultRow                 in ROMESQL::ReadField  
    char* c                          in ROMEString::SetFormatted  
     int istart,iend,iValue,jValue   in ROMEXMLDataBase::Read  
    int istep,iValue,jValue          in ROMEXMLDataBase::Write  
    ROMEStrArray *array              in ROMEXMLDataBase::Write  
  
(2) Following points are not fixed yet.  
* There can be unused "int i" in several codes which builder generates. (ex. XXAnalyzer::InitMidasBanks  
)  
  This is not a problem, but a little bit annoying. If it is very easy, please fix it. 
  
* Please make sure this is not a problem.  
   in ROMEAnalyzer:: ResponseFunction  
      while (obj = iterFolders->Next()) {  
            ROMEString str;  
            str.SetFormatted("%s",obj->GetName());  
            names->Add(new TObjString(str.Data()));  
      }  
  
*ROMEString.cpp:74: warning: `int numberOfDigits' might be used uninitialized in this function  
*ROMEXMLDataBase.cpp:80: warning: `ROMEXML*xml' might be  used uninitialized in this function  
  
  
(3) This is not warning from g++, but request from me.  
  If it is very easy, please make ROMEString::SetFormatted,AppendFormatted to check that number of  
arguments is correct.
