Looks like Windows still wants those symbols exported.

@brettcannon Is there libffi-8.dll in $(ExternalsDir)libffi-3.4.2 runner directory when a GitHub action fails (as declared in libffi.props)? I cannot say "the library is present because other imports are resolved" since ffi_type_* look like the only ffi exports. At least there is no other declaration with FFI_EXTERN in headers before generation.

No idea.

Steve explained the issue on BPO. Windows cannot statically reference values from a DLL.
