I think in C you can skip the cast from void *, can't you?  e.g.

liteSCardEstablishContext =
wine_dlsym(g_pcscliteHandle,"SCardEstablishContext",szErr,sizeof(szErr));
if (!liteSCardEstablishContext)
{
    ERR("Failed to get SCardEstablishContext from pcsclite library.
Error = %s\n",szErr);
    goto error;
}
