But you do use VC compiled GDAL DLL? HDF5 seems to be available in many 
formats (for cygwin, vs2005, etc). I'm just looking at a hdf5dll.dll and 
it does not export anything in C++, while gdal16.dll does. I believe gcc 
is not able to decrypt the way VC exports C++ methods, which you are using.

Why don't you use the GDAL DLL that you get from compiling it with MinGW?
