Good day, The following makefile prints 'B' instead of 'A'.
a := A
%bar : arg := $a
%bar : ; @echo $(arg)
a := B
foobar:
Patch is attached for those who find this behavior surprising.
Also note that this patch does not address the following cases:
%bar : a := a
%bar : $a_b := a_b # doesn't work, equivalent to _b := a_b
%bar : a := a
%bar : a_b := $a_b # doesn't work, equivalent to a_b := _b
comments are welcome,
