That's why you combine it with -Wno-... as appropriate on a per-project as well as per-file basis in addition to a simple way to disable warnings completely. When using make, it could look something like this: CC := clang CFLAGS := -std=c99 WFLAGS := -Weverything -Werror NOWARN := vla COMPILE = $(CC) -c $(CFLAGS) $(WFLAGS) $(NOWARN:%=-Wno-%) -o $@ $< foo.o: NOWARN += padded foo.o bar.o: %.o: %.c $(COMPILE) Building without warnings would be achieved via make WFLAGS=""
