Details:

In file included from /junk/AVR/uracoli/install/inc/ioutil.h:57,
                 from project.h:8,
                 from fb.c:4:
/junk/AVR/uracoli/install/inc/hif.h:74: warning: useless type name in empty
declaration

This is due to:

#if HIF_TYPE != HIF_NONE || defined DOXYGEN
...
#else
# define hif_init(br)
...
#endif
...

void hif_init(const uint32_t baudrate);

Even if HIF_NONE is a pointless usage case, it should not
result in an empty definition inside the header file, which
eventually turns out to be:

void ;
