As a workaround: in gst/gst_private.h, at line 55, change

#define IMPORT_SYMBOL __declspec(dllimport)

into 

#define IMPORT_SYMBOL


I've got gstreamer-0.10.9 to build with this hack, and it seems to work,
at least for the simple pipelines I've tried. I don't know exactly the
reason for the build failure (I'm not a Win32 expert), but "__declspec"
might not be needed for MinGW.

Note: this change might break the Visual C++ build...
