Bug report: http://www.salome-platform.org/forum/forum_10/636759606
Fix compilation warnings:
- unused function
- missing virtual destructor
- variable set but not used
1) Fix common WIN32 compilation errors.
2) Replace WNT deprecated macro definition by the WIN32.
3) Remove unnecessary test executables.
4) Make MEFISTO2D algorithm optional: try to determine f2c generator and generate C code from Fortran, otherwise MEFISTO2D is unavailable.
