great about extending a class.
valac build 2 ansi c source files, but it understand it's a only class
and put all source code in file1.c.
This is great because we can put signals in different vala files for
examples. Extending classes itś great for me.

vala2.c file itś empty:

All source code itś in vala1.c file :
/* Basic Vala Sample Code */

#include <stdlib.h>
#include <string.h>
#include <stdio.h>

SAMPLE_DUMMY_PROPERTY
