duplicated definition for a target

[Lin George]

Hello everyone,


I thought duplicated definition for a target is not
correct. But it seems that it is ok to define a target
more than once. See this sample Makefile (I defined
Foo twice),

--------------------
Goo:
        @echo "Goo"
Foo: Goo

Foo:
        @echo "Foo"
--------------------

when I execute make Foo, the output is,

--------------------
Goo
Foo
--------------------

So, my question is that. Is it ok to define a target
more than once? Always ok or under some conditions?


thanks in advance,
George
