If you're developing your project as VC++ standalone project, codes
in tutorials and contrib modules don't work at all, because they
don't have __declspec(dllexport) for each function and variable to
be exported. They will work well as long as you use mingw or special
VC++ environment used to build the core.

I had the same problems before, and I wrote some hacks for VC++.
The codes in pg_reorg/lib in pgFoundry might be a help:
