Hiya, just a quick note to say that wepdecrypt builds the wkeygen file with the libraries listed before the wkeygen.c file. That means that --as-needed removes the libraries before they're referenced causing errors during the linking stage. The patch simply re-arranges where the $(LIBS) argument comes in the Makefile.
