This concerns the scope of function parameters when using the
flavor() function to see if they are defined.

Consider the following functions and subsequent calls:

inner =\
$(info 1F="$(flavor 1)" 1V="$(1)" 2F="$(flavor 2)" 2V="$(2)")
outer = $(call inner,one)

$(call outer,one)
$(call outer,one,two)

This will produce the following output with make-4.2.90

1F="simple" 1V="one" 2F="undefined" 2V=""
1F="simple" 1V="one" 2F="simple" 2V=""

It appears that the scope of the parameters in the outer function intrudes into the inner function for the flavor() function but not for the value of the parameter.
