All, Thank you for the suggestions. And to clarify: yes this is an MSVC build so -fvisibility=hidden is not an option. I am currently investigating adding a def file to curate the symbols exported by the gdal dll. I removed the decorated symbols and built. The resulting dll still reports the decorated symbols, but I'm hopeful that this is expected behavior. I'm going to attempt to remove the libspatialite symbols from the def file and rebuild,
