I would prefer the int res SPICE_GNUC_UNUSED method.
Currently there are no other reasons for Glib dependencies and not clearing
the screen is not such issue, actually would be much more confusing to
see a message in the middle of the output.
Personally the best option would be
(void) system("clear");
which should be the standard C way... only if it worked on gcc...
Oh... another solution could be something like
if (system("clear") != 0) {
printf("\n\n\n");
}
