compilation error on 13.07.01 release

hi,
i tried in lot of ways to install your application on my laptop, but without any success:

1) I tried downloading the 13.07.01 release version, running ant command ("ant" and "ant load-demo") but compiling errors appears (i lost them in the dos screen, i haven't captured)
2) I Tried downloading head trunc of 13 version but "use -Xlint:unchecked" error appeared

so

1) reading solutions on the net (here: OFBIZ-5835) I found an answer that sayed to use javac 1.7 for compiling: modified macros.xml for use javac17 and modified references in 2 build.xml files finished compiling errors

2) modified macros.xml file to add the Xlint:unchecked (simply uncommented the existing one) option to the compiler but compilers errors appeared

how to solve?

I will try to execute the compiling process the same way of the link above, with the same version of ofbiz (1633686 revision) and 1.8.0 java sdk...otherwise i don't know how to do
