The error messages say:
packet-myudp.c(90) : error C2220: warning treated as error - no 'object' file generated

The difference in the makefiles is that you don't have the "warnings treated as error" turned on in the modified file, but that's not the correct modification to make.  The correct way to address this is to fix the warnings in packet-myudp.c as pointed out by the compiler.  They look like mostly minor things that would only need a few minutes to address and your code will be better quality as a result even though it may work as intended already.
