I just found I can eliminate the errors by simply moving $(eval ...)
out of ifdef ... endif, for GNU Make version 3.80
-------------------------------------------------------------------------------------------------------------
my_src_dir := dir_a dir_b

define dir-to-vpath
#X
vpath %c $1
vpath %S $1
#Z
endef

ifdef my_src_dir
cmd = $(foreach dir,$(my_src_dir),$(call dir-to-vpath,$(dir)))
$(warning $(cmd))
endif
$(eval $(cmd))

all: 1.c 2.c 3.S
-------------------------------------------------------------------------------------------------------------
Maybe it is a bug for version 3.80 and has been corrected on 3.81 and
later versions
