    gom: Fix build with C++ compilers
    
    By moving enum typedefs after the enum definition.
    
    Putting the typedefs above the enum makes compilation fail for C++ programs. Example error:
    
    /gom-filter.h:38:14: error: use of enum ‘_GomFilterMode’ without previous declaration
     typedef enum   _GomFilterMode    GomFilterMode;
                   ^
