If the Makefile contains these lines then it builds the DLL correctly on windows-x64-static.  dumpbin /exports shows the correct exported symbols.

My guess is that if you restored the .def file(s) that might fix it – don't they provide the linker with a list of symbols to export? The other solution would be to decorate all the symbols that need to be exported inside the source code, but that’s going to take more work.
