Ah, do you mean that there may be globally applicable internal
setting? I would have expected that such an option would be done
directly on the command line, e.g.
$(SP_OBJ): %.sp: %.c GIT-CFLAGS FORCE
$(QUIET_SP)cgcc -no-compile $(ALL_CFLAGS) $(EXTRA_CPPFLAGS) \
$(SPARSE_FLAGS) $(SP_EXTRA_FLAGS) \
-Wsparse-settings-for-everybody $<
But it is fine either way, as long as the purpose of the macro is
documented clearly enough ;-)
Thanks.
