I believe this is due to the version of GCC you are using to compile the project with, that and the fact that the project hasn't been touched in a few years.
GCC is treating all warnings as errors, easiest solution is to tell GCC not to treat implicit-fallthrough warnings as errors.

During the ./auto/configure step, add this flag --with-cc-opt="-Wno-error=implicit-fallthrough"

It's resolved. Thanks for your help.
