I've got the following makefile:
define reverse-list
$(if $(strip $(1)), \
$(call reverse-list,$(call pop-front,$(1)),$(firstword $(1)) $(2)), \
$(2))
endef
good-wrapper = $(call reverse-list,$(2),)
bad-wrapper = $(call reverse-list,$(2))
.PHONY: all
all:
echo $(call good-wrapper,,a o e u)
echo $(call bad-wrapper,,a o e u)
with the following behaviour:
piias306 /ms/user/y/yapn/proj/aoeu 77$ gmake
u e o a
u e o a a o e u
Is this a bug, or an undocumented feature?
Thanks,
Noel
