We've always used both. See Makefile.global.in:
ifeq ($(GCC), yes)
CFLAGS += -Wall -Wmissing-prototypes -Wmissing-declarations
endif

Hmm, it looks like -Wmissing-prototypes may be a superset of
-Wmissing-declarations --- it seems to say that the latter will be
content with a K&R style declaration ("extern int foo();") but the
former will not. If that's a correct reading then we could drop
-Wmissing-declarations.
