If you think so,  the following also depends on the impilementation
of <stdbool.h>, doesn't it?

#define _STDBOOL_H

#include <common.h>
#include <command.h>


For example, if <stdbool.h> used
_STDBOOL_H_  or  __STDBOOL_H  instead of _STDBOOL_H,
<stdbool.h> would be included and 
common/cmd_test.c  would not be compiled correctly.

Yes. Your patch fixed the build error.
