Compile failure

The KA04 sample code compilation on Uno with the VMA04 installed was unsuccessful and the first signs of this outcome
were the following linesin the printout

EtherCard.cpp: In static member function ‘static word Stash::cleanup()’:
EtherCard.cpp:267: warning: no return statement in function returning non-void
EtherCard.cpp:267: warning: control reaches end of non-void function
EtherCard.cpp: In static member function ‘static void Stash::extract(word, word, void*)’:
EtherCard.cpp:198: warning: ‘ptr’ may be used uninitialized in this function

The diode is blinking as the blinking led programme was installed first and I thought
that programming ought to be erased before but I could not find anything about this in
the documentation

Even though the warnings are correct, it compiles without these warnings in the Arduino IDE 1.0.6

Also, if you know how, you can try the latest version of the EtherCard library from GitHub

Perhaps they made some updates to fix this
