I'm not familiar with Cygwin (or Windows) dll.
Maybe create an import library libzsh.a?
Or explicitly dlopen("libzsh.dll") from the param_private.dll and
call dlsym("gethashnode2") ?

realparamtab->getnode is already saved in getparamnode in your
original code, and getparamnode() (not gethashnode()) is called
in getprivatenode().
On the other hand, gethashnode2() is called in getprivatenode2().
