+                !(liteSCardEstablishContext =

pcsclite library. Error = %s\n",szErr);
+            }

This would be a lot cleaner as:

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

....

return TRUE;

error:
    wine_dlclose(g_pcscliteHandle,NULL,0);
    g_pcscliteHandle = NULL;
    return FALSE;
}
