[svn-r6772] 
Purpose: Windows maintenance and code cleanup

Description: There were a lot of places in the source code where varibale
             was declared but never used.

Solution: Cleaned the source code to avoid warnings on Windows adn Unix
          platforms.

Platforms tested: arabica, modi4, Windows
                  Probably my environment is wrong on Linux, cannot
                  compile at all when fortran is enabled
                  If daily tests fails tomorrow, this will be my fault
                  but I want to go home now :-)
