swig extension compile error with "format not a string literal and no format arguments"

[Markus Neteler]

After update to Mandriva 2009.1, extensions/gdal_wrap.cpp no longer compiles/installs:

make install
...

The function there is

  void Debug( const char *msg_class, const char *message ) {
    CPLDebug( msg_class, message );
  }

Additionally, I see during compilation:

[neteler@host550 swig]$ make

(maybe worth fixing, too)

Waou. We create the same bug at the same time. Closed as a duplicate of #2974
