    _______________________________________________________

Details:

The private modifier should suppress inheritance of target-specific variables,
but this does not seem to always work.

In a chain of dependant targets, if more than one target modifies a private
target-specific variable, then the later target in the chain inherits the
private variable from the earlier target.

Building the attached makefile with GNU Make 3.82, I get the following
output:

bar3: FOO 1 3
bar2: FOO
bar1: FOO 1

I was not expecting the private value of DEFS used by target 'bar1' to be
inherited and used when creating the private value of DEFS for target 'bar3'. 
The output I expected was:

bar3: FOO 3
bar2: FOO
bar1: FOO 1

The attached makesimple is probably a simpler example and I expected it to
give the following output:

bar3: 3
bar2: 
bar1: 1

regards,
Rob.
