Ok, that's the kind of thing I was thinking of.

And indeed with C++, the new prototype

  int module_speak(const char *data, size_t bytes, SPDMessageType msgtype);

doesn't match the old prototype that you still use:

  int module_speak(gchar *data, size_t bytes, SPDMessageType msgtype) {

In C they are compatible, but in C++ they are different. And
unfortunately it seems that C++ insists on making your function a C++
function, not a C function, thus with name mangling, and thus the
missing weak reference to module_speak.

I have now fixed this in the master tree, please retry.
