These are not really unused. A few lines later it reads:

#include "../src/inflate.c"

These macros are used within inflate.c

(and perhaps the inclusion of inflate.c is not a good idea, maybe this
should be in lib.a
note that inflate.c is also included in init/do_mounts_rd.c;
fortunately this is all init code (which is probably why include was
used in the first place))
