That's a Win-specific error.
When we create libmysqld.dll we have many libraries like mysys, dbug,
strings, etc linked into that dll, so the application built upon
this library shouldn't link these libraries to itself, rather use
those inside the dll.
Fixed by redirecting calls into the libmysqld.dll
