This makefile demonstrates a bug in the expansion of .VARIABLES:
$ cat Makefile.variables
MY_one := 1
MY_two := 2
$(foreach v, $(filter MY_%, $(.VARIABLES)), $(eval undefine $v))
MY_foo := foo
MY_bar := bar
all:; @echo MY Variables = $(filter MY_%, $(.VARIABLES))
$ make -f Makefile.variables
MY Variables = MY_one MY_two
