Files input_formatter_subsystem_defs.h begin with:
    #ifndef _if_subsystem_defs_h
    #define _if_subsystem_defs_h__
and end with:
    #endif /* _if_subsystem_defs_h__ */
The intent seems to have been to use _if_subsystem_defs_h__ everywhere
but two underscores are missing in the initial #ifndef.
