I guess those are the Microsoft tools, not the gnu ones. The makefiles 
are set up for some version of MSVC. I find it easier to use VisualC++ 
Express (which you can get for free) to build pd stuff for Windows, 
MINGW being such a pain to set up. Setting up a project in VC is only 
about 90% the hassle of redoing the makefile...;(
I'm not sure (!), but I don't think MINGW dlls will work with binaries 
built with Microsoft tools.
The 'couldn't load' message may relate to that. One way to find out 
would be to build pd first and try linking to the pd.lib you get from that.
The other cause of externs not loading is that the setup routine is not 
exported, something which is done differently in MINGW vs MSVC.
