How about something like this.
function = \
$(foreach .i,$(1), \
$(if $(strip $($(.i))),$(warning cool),$(error blargh!)) \
)
a := 1
b := 2
c :=
$(warning 1)
$(call function,a b)
$(warning 2)
$(call function,a b c)
$(warning 3)
Outputs,
GNUmakefile:12: 1
GNUmakefile:13: cool
GNUmakefile:13: cool
GNUmakefile:14: 2
GNUmakefile:15: cool
GNUmakefile:15: cool
GNUmakefile:15: *** blargh!. Stop.
