As I recently installed versions 4.6.1 and 4.6.2, I had a hunch that might be the cause. The installation of MinGW 2010 on my PC comes with gfortran 4.5. Running CMake and make with that version of gfortran built all examples smoothly (well, there were some enigmatic warnings about the COMMON blocks, but they were accompanied with a reassuring message that the fix should in general work) and the programs were nicely built. My conclusion right now is that gfortran 4.6.x is causing the trouble. We do not need anything more than the -Wl,--allow-multiple-define option by the way, so if all else fails, we can greatly simplify these extra files. I am going to try and find out why these gfortran routines are incorporated in the DLL and if there is a way to prevent that.
